Magnetic Folding Door Holder Specification: Door-Surface Fit and Deployment Checks for Importers

For procurement, the magnetic folding door holder specification starts with the exact reference parts and intended arrangement. A magnetic folding door holder specification should identify the intended door surface, the product’s magnet contact, the deployed floor prop and the clearance needed when the prop is stored. The item is a small assembly with two different interfaces: a door attachment and a movable contact near the floor. Buyers should approve the model in the actual door-and-floor configuration rather than assume that any magnet-compatible surface or gap will work.

This article is a sourcing and sample-review guide for an explicitly suitable ordinary interior application. It is not an installation manual, code interpretation or recommendation for fire doors, smoke doors, emergency routes, access-controlled doors, regulated hold-open devices or accessibility applications. Selection for those uses belongs to the responsible qualified project team. The guidance makes no claim about holding force, slip resistance, cycle life, damage prevention or current Koitor product availability.

What is the product’s actual operating function?

A fixed floor bumper protects a door or nearby wall from direct impact. A folding door prop has a movable part that contacts the floor in a deployed position and returns to a stored position when the door moves. A regulated hold-open device may serve a separate building or life-safety function. Buyers must keep these product types distinct: a magnetic folding prop is not automatically a compliant hold-open device and should not be described as one.

The magnet is only one element of the assembly. The door attachment must meet a compatible surface and contact region. The prop must reach the floor in its intended operating position. The hinge, pivot or folding link must move through a clear path. The stored product must not interfere with normal door swing or nearby objects. The buyer should define the application before comparing product options.

Manufacturer listings illustrate why a model-specific review matters. Yamazaki’s Tower magnet doorstop, model H10153, describes a powder-coated steel body with silicone contact sections and a magnet, and states a limitation to flat steel doors with magnetic compatibility. Yamazaki’s second metal folding model, H10871, has its own stated door-gap limitation and its own deployed and stored dimensions. These supplier details belong to those named products, not universal design rules. They do not establish performance for a different model, surface or floor.

An importer should capture the exact reference model and exclusions before drafting product copy. Avoid translating a model-specific phrase into “fits all steel doors” or “works on any floor.” The buyer’s SKU master should identify the intended application, compatible surface description, product revision and documentation source. If multiple door or flooring variations are planned, each should be reviewed separately.

How should the door surface and magnet contact be described?

The term “metal door” does not settle magnet compatibility. A door may include a non-magnetic face, an internal core that is irrelevant to the exposed contact surface, a coating, a textured region or a panel shape that prevents full contact. The supplier’s instructions and drawing should identify the surface for which the model is designed. If the buyer’s door is not clearly covered, ask the responsible manufacturer or project team before making a fit statement.

Record the door material as confirmed by the relevant supplier or facility owner. Photograph the intended contact region and note its flatness, finish, trim, seams, recesses and curvature. The magnet or contact pad should meet the actual face in the position shown by the product instructions. Do not assume that a magnet touching a steel hinge or a concealed frame proves the product is compatible with the door skin.

The magnet, silicone or other contact component may be purchased from another supplier. Identify who provides it and who controls its part number, revision and replacement. Do not claim Koitor manufactures the magnet, supplies a particular silicone compound or has tested a holding force unless approved company records establish that fact. Any supplier statement about non-marking contact or surface protection should be treated as product-specific and verified against the buyer’s actual finish.

The matrix structures an RFQ; it does not set a universal door gap or magnet strength. Numeric limits must come from the exact model’s controlled information and an agreed sample. Keep the evidence connected to the buyer’s specific door and floor scenario.

What should be checked in the deployed position?

The deployed sample should be reviewed on the intended door and floor arrangement or on a representative mock-up approved by the responsible supplier. Confirm the product is installed or placed only as directed by its manufacturer. This article does not provide consumer fitting instructions. The buyer’s goal is to document whether the exact model, door and floor can be assessed under the product owner’s intended use.

Observe where the prop foot touches the floor, whether the contact occurs in the intended location and how the door, foot and floor relate at full deployment. Note if the door-to-floor distance, floor transition, threshold, rug or surface texture changes the contact. A visual alignment is not proof of holding performance. If a project needs a performance criterion, the supplier and buyer must define the test and acceptance conditions in advance.

Check the operation path without inventing a pass force. A foot-operated element, if present, should be observed according to the manufacturer’s stated operation. Record whether the user’s foot, the door leaf or another part of the assembly follows the intended movement. Do not claim ease of operation, accessibility or safe behavior based on an informal demonstration. Those conclusions require appropriate project and product evidence.

The buyer should also note what happens when the door is moved from the deployed condition. Does the prop return to its intended position? Does any component touch the finished door or trim in an unexpected way? Is there a location where the moving member may contact a wall, skirting, furniture or another fixture? The observation should match the exact sample model and review protocol.

A useful sample sequence is:

1. Confirm the model, revision, instructions and buyer application.
2. Confirm the door and floor mock-up represent the intended installation.
3. Photograph the surface and door-to-floor relationship before review.
4. Position the product according to its supplier’s instructions.
5. Observe the deployed foot location and door contact area.
6. Move through the permitted operation sequence and note contact or interference.
7. Check surrounding objects and the normal swing path.
8. Return the prop to its stored condition as directed.
9. Repeat only as specified in the supplier’s agreed review method.
10. Record observations, exclusions and the responsible approver.

This list is not a cycle-life, load, friction or safety test. Do not translate it into “tested to hold” or “will not slip.” A particular observed arrangement is only that arrangement. Any stronger claim needs a defined method, conditions, results and authorization from the responsible party.

How does the stored position affect the product fit?

A folding prop has an envelope when it is not deployed. Buyers should compare that envelope with the door swing, nearby wall, trim, skirting, furniture, wall-mounted hardware and packaging. A product that remains attached to a door may pass through a doorway or move near another surface. The sample should be observed across the intended swing path using a representative mock-up. Do not assume that the attachment position is acceptable simply because the deployed prop reaches the floor.

Ask the supplier for separate dimensions and orientation references for the stored and deployed configurations. Keep the door gap, magnet location, hinge position and prop length with the drawing revision. Model H10153 and model H10871 from Yamazaki publish different configurations and limitations, illustrating why one model’s dimensions cannot be applied to another. Their listed values should be checked on the live product documentation before a specific purchase decision; they are not target dimensions for a private-label design.

For an assortment, build a compatibility table with each intended application. A product team may have painted timber doors, flat steel doors, doors with trim, differing floor surfaces and multiple threshold heights. It should not group them together as a single universal compatible environment. Use a “reviewed,” “not reviewed” or “excluded” status that describes the evidence. Do not imply compatibility based on the word “magnetic” in a product name.

A replacement purchase should also respect the exact model and mounting or contact setup. If the buyer changes the door panel, floor finish, prop, pad or magnet component, re-evaluate the interface. Keep sample sign-off, supplier instructions and SKU information available to customer service so they do not recommend a substitute based only on visual similarity.

Which claims and applications must stay out of scope?

A buyer should not use this guide as a substitute for fire-door or smoke-door selection, emergency egress planning, access control or a regulated hold-open requirement. Those applications may involve code, building operation and life-safety consequences. The appropriate architect, facility owner, fire-safety professional or qualified project authority must decide which hardware is permitted. A consumer doorstop description does not establish suitability for those functions.

Likewise, no universal claims about magnetic strength, non-marking contact, floor grip, weight capacity, durability or “stays in place” can be drawn from a catalog photograph. A supplier may provide a particular test or product statement; the buyer should record its method, model and conditions. Do not carry claims from a named Yamazaki model to an unbranded private-label design.

The buyer can ask for metal-frame feasibility support while keeping purchased parts identified. Koitor’s documented forming, punching, welding, finishing, assembly and packaging knowledge may support a discussion of metal components within an approved scope. It does not prove current Koitor production of door holders, magnets, silicone parts or a proprietary branded mechanism. For general company context, see the pages on fabrication sur mesure de rayonnages métalliques de stockage et OEM home storage hardware.

What should the importer include in the RFQ?

Provide the actual door or an approved representative sample, the confirmed surface description, door-to-floor relationship, intended floor, product application, nearby obstacles, storage condition, model constraints and required pack configuration. If the buyer is requesting a custom metal part, add the original concept drawing, finish reference, intended magnet or pad supplier and the authority responsible for approving the application. Mark every assumption that remains unverified.

Ask the supplier to state which door surfaces the model is designed for and what dimensions control its fit. Request a current drawing that distinguishes deployed and stored configurations and shows the contact components. Confirm which pieces are included, which are optional, and who supplies any purchased magnet, silicone section, hinge or fastener. Obtain the care and operating information from the responsible product supplier.

A production approval record can include:

• Finished SKU, model and drawing revision.
• Intended ordinary-door application and explicit exclusions.
• Door material source and actual contact-surface photos.
• Door-to-floor relationship and floor description.
• Deployed foot contact and operating path observations.
• Stored position and door-swing clearance.
• Magnet, silicone, hinge and hardware supplier references.
• Supplier instructions, care and replacement parts.
• Sample review method and authorized acceptance owner.
• Packaging, labeling and approved change triggers.

Keep the sign-off linked to the exact product and application. If a different door or floor environment becomes part of the target market, treat it as an additional review rather than broadening the compatibility statement without evidence. A product copywriter should receive the same limitations as the buyer and should not turn a model-specific constraint into a general promise.

A well-defined purchase decision answers four questions: Is the intended application within the model’s stated scope? Does the magnet meet the actual approved door surface? Does the prop contact the intended floor in the deployed configuration? Is the stored product clear of the door’s normal movement and nearby objects? If any answer is unknown, keep it as an open approval item.
