Bifold components are often specific to the original door system, so compare the manufacturer, part shape, fixing centres and measurements before ordering. If you cannot identify the part, use our window and door part identification service and send us clear photos and measurements.

How to Identify the Correct Bifold Door Hardware
Unlike many standard door components, bifold hardware is commonly designed around a particular aluminium or door profile system. Two hinges, rollers or gearboxes can look almost identical but have different fixing positions, dimensions or interfaces, so it is better to identify the original system and measure the part than to choose by appearance alone.
- Look for the system or manufacturer. Check the door, existing hardware and paperwork for names, logos or part numbers.
- Photograph the complete component. Take front, side and fixing views before removing anything.
- Measure the critical dimensions. Depending on the part this can include screw centres, overall height and width, spindle size, PZ/backset, rod diameter or roller dimensions.
- Check its position. Note whether the part is a top guide, bottom roller, intermediate-panel component, end panel component, open-in/open-out part or left/right handed.
- Compare the product specification. Use the diagrams and compatibility information on the individual JCP product page before ordering.
Not sure what you have? Send us several clear photographs, including any markings and a ruler or tape measure for scale, through our part identification service. Bifold systems can be difficult to identify from one photograph, so the more detail you provide, the better.
Bifold Door Rollers and Top Guides
Bottom rollers and top guides keep the folding panels supported, aligned and running accurately in the track. Worn bearings, damaged wheels or incorrect adjustment can contribute to doors becoming heavy, noisy or difficult to fold. Our range includes system-specific replacement assemblies for a number of popular bifold systems, so always match the existing hardware and door system carefully.
Bifold Door Hinges
Bifold hinges connect the folding leaves and must maintain the correct relationship between adjacent panels as the doors open and stack. Replacement hinges can differ by system, opening direction, profile and fixing centres. Some bifold systems also use hinge assemblies incorporating pull handles.
Bifold Door Handles
Bifold door handles include handles for intermediate locking panels as well as pull-handle and hinge-handle designs. Intermediate handles may operate shoot-bolt gearboxes which secure the panel at the head and sill. Check the spindle diameter, screw centres, backplate dimensions and whether a locking or non-locking handle is required.
Bifold Door Locks and Shoot-Bolt Gearboxes
Bifold door locks and gearboxes can operate locking rods or shoot bolts at the top and bottom of an intermediate panel, while other bifold doors use more conventional hook or multipoint arrangements. Replacing a failed gearbox or locking component can often repair the existing door without replacing the complete door set. Compatibility dimensions such as PZ, backset, spindle, screw centres and rod connection size vary by design.
Bifold Door Catches and Hold-Backs
Bifold door catches hold adjacent panels together when the doors are folded open. Magnetic and mechanical hold-back designs can help stabilise the stacked panels and reduce unwanted movement. Check the stand-off or overall height, particularly where the catch must clear a lever handle or other hardware.
Bifold Door Accessories
Bifold accessories include system-specific spare components such as shoot-bolt guides and cones, covers, fixing components and other repair parts. Small components can be critical to correct locking and alignment, so match the system and dimensions before ordering.
Popular Bifold Door Systems
JCP stocks replacement hardware used across a range of established bifold systems. Depending on the component, this includes parts for systems such as Debar A1 and V1, Smarts/Exlabesa Visofold, Cortizo, DeWall, Alunet, Alutech, Eurocell, AluK BSF70, Sheerline, Reynaers RCF68, Stellar, WarmCore and Liniar. Compatibility is product-specific, so the presence of a system name in this range does not mean every part will fit every version of that system.
Frequently Asked Questions
Why has my bifold door become difficult to slide or fold?
Heavy or uneven operation can be caused by worn rollers or bearings, incorrect adjustment, a damaged guide, hinge wear, track contamination or door-panel alignment. Inspect the hardware and track before ordering a replacement part rather than assuming the roller is always the cause.
Can I replace just one bifold door roller or hinge?
Often yes, provided the correct replacement component is available and the rest of the system is serviceable. Because bifold hardware is frequently system-specific, compare the existing component and check the product compatibility information carefully.
What should I measure on a bifold door lock or gearbox?
The important dimensions depend on the design but can include the gearbox body size, spindle diameter, handle screw centres, PZ, backset, shoot-bolt throw and rod connection diameter. Use the measurements shown on the individual product page as your checklist.
What is a bifold door magnetic catch for?
A magnetic hold-back catch connects adjacent panels when the bifold door is stacked open. It helps keep the panels together and reduces unwanted movement while the door set is open.
How do I know which bifold door system I have?
Look for logos, labels or codes on the hinges, rollers, lock, handles and aluminium profile. If no identification is visible, photograph the existing components from several angles and include measurements. Our part identification service can help narrow down the correct replacement.
