This is the Knape & Vogt Interlok anti-tilt cable accessory for 4-high lateral file drawer systems, designed to work with the 8500T, 8505T, 8520T, and 8525T series. It mechanically prevents more than one drawer from opening at a time, eliminating the forward tip-over risk that an overloaded tall lateral file presents when multiple heavy drawers are pulled out simultaneously.
A 4-high lateral file loaded with hanging folders and binders carries significant forward weight in every drawer. Without an anti-tilt mechanism, opening two or more drawers at once can shift the cabinet's center of gravity past its tipping point — a real hazard in a busy office or commercial filing room. The Interlok cable threads through the drawer system so that as soon as one drawer opens, the cable tension blocks the remaining three. The heaviest-use case for this accessory is commercial office builds and institutional filing installations where tall lateral files are anchored to a wall or run in a row, and where compliance with workplace safety expectations calls for a documented anti-tilt feature built into the hardware rather than relying on user habit.
The cable accessory is made to integrate with the 8500T series lateral file drawer system's internal hardware. Because lateral file drawer systems from different manufacturers use different interlock geometries, this cable is specific to the KV 8500T, 8505T, 8520T, and 8525T series — it is not interchangeable with other brands or other KV series outside that group. Ordering the correct series match is the only fit decision required; the cable installs within the system's existing structure.
Commercial casework installers completing a lateral file build on the KV 8500T system should include this cable whenever the specification calls for four drawers in a single lateral unit. Office furniture dealers retrofitting or repairing existing 8500T-family installations will find this the right replacement or add-on part. Facilities managers sourcing safety hardware for tall lateral files in open-plan offices and institutional environments — schools, hospitals, government — will want this accessory specified as part of the drawer hardware package rather than addressed after installation.
No — this accessory is sized and configured for 4-high lateral file systems in the 8500T, 8505T, 8520T, and 8525T series. A different cable accessory is required for other drawer counts; confirm the correct part against your specific file height before ordering.
The accessory is designed to integrate with the 8500T series drawer system, so it can be added to an existing installation — the cable routes through the system's internal framework. Access requirements will depend on how the cabinet is built and anchored.
No. The Interlok cable is engineered for the KV 8500T, 8505T, 8520T, and 8525T series specifically. Lateral file interlock geometries are not standardized across brands or series, so a cable from one system will not function correctly in another.
The listing is for the cable accessory unit for one 4-high lateral file system. Confirm the quantity required against your project before ordering.
Specifying the Interlok anti-tilt cable as part of the drawer system — rather than relying on posted reminders or procedural controls — keeps tall lateral files stable and compliant with workplace safety expectations from the moment the first drawer is pulled.
