Bi-fold door hardware must be selected as part of the complete aluminium door system. Rollers, carriers, hinges, guides, handles and locks work together to support the panel configuration and movement. Hardware should not be chosen independently from the door frame, panel size and glass weight.
Main Bi-fold Door Hardware Components
- Carriers and rollers: support and guide the moving panels within the compatible track system.
- Hinges: connect panels and allow them to fold as the door opens.
- Top and bottom guides: maintain alignment through the operating cycle.
- Handles and locks: provide operation and secure the nominated active panel.
- Flush bolts or compatible locking points: may secure selected panels in a multi-panel configuration.
- Stops, seals and accessories: coordinate panel travel, weather sealing and finishing details.
Hardware Must Match the Door Configuration
Bi-fold doors can use different panel numbers, folding directions and active-door arrangements. The hardware schedule must match the approved configuration. Panel dimensions, glass makeup, total weight, frame system and wind requirements can affect compatible carriers, hinges and locks.
Do not assume that a component from another bi-fold system can be substituted because it looks similar. Hole positions, load paths, profiles, tracks and adjustment methods may differ.
Thermally Broken Bi-fold Door Hardware
JL Thermal bi-fold doors use hardware compatible with the selected thermally broken aluminium system. The insulating section in the frame, panel construction and seals must remain coordinated with the hinges, carriers and locking components.
See our thermally broken aluminium bi-fold doors Melbourne page for complete door configurations, glazing and quotation information.
Operation and Adjustment
Bi-fold doors contain multiple moving and connected panels. Correct installation, alignment and adjustment are important for panel movement and consistent clearances. If a door becomes difficult to operate, avoid forcing the panels or altering hardware without identifying the cause.
Bi-fold Door Hardware Maintenance
- Keep tracks and drainage paths free from dirt and debris.
- Clean aluminium, handles and accessible hardware with suitable mild products.
- Check for loose fasteners, unusual movement or damaged seals.
- Use only lubricants and adjustment methods recommended for the selected hardware.
- Arrange assessment if panels drop, bind or no longer lock consistently.
Confirming Replacement Hardware
Replacement components should be identified from the original door system, hardware markings, photographs and measurements. Availability can change over time. A complete site assessment may be needed where the existing hardware is damaged, discontinued or no longer compatible with the panels and tracks.
