The Knape and Vogt Interlok Anti-Tilt Cable is a safety accessory for 3-high lateral file cabinet systems, designed to work with KV 8500T, 8505T, 8520T, and 8525T lateral file drawer slides. It mechanically prevents more than one drawer from opening at the same time, eliminating the tip-forward hazard that comes with a fully loaded lateral file when multiple drawers are extended.
Lateral file cabinets carry concentrated weight in every drawer — hanging folders, binders, and documents that shift forward when a drawer opens. In a 3-high configuration, pulling two drawers open at once creates a forward tipping moment that can topple the cabinet. The Interlok cable threads through the drawer system and physically releases only one drawer at a time, so the cabinet stays stable under load. This applies in offices, workrooms, legal departments, and any workspace running lateral files on KV's 8500-series slide program. If the cabinet is 3-high and uses any of the four compatible slide series, this is the specific cable that belongs in it.
This cable is part of the Knape and Vogt Interlok program and is engineered for the 8500T, 8505T, 8520T, and 8525T lateral file drawer systems. The Interlok system is series-specific — cables, linkages, and hardware from other KV programs or other manufacturers do not substitute for it. The 3-high cable is a single cable accessory matched to a three-drawer lateral file stack; the two-drawer and four-drawer heights use different cables sized for their respective configurations. Confirm your drawer count before ordering: a cable sized for the wrong stack height will not function correctly in the interlock sequence.
Design professionals and facility managers specifying lateral file systems for office buildouts should include the matching anti-tilt cable as a required accessory alongside the slide sets — it is a safety component, not an optional upgrade. Cabinet shops building lateral file furniture on KV 8500-series hardware need one cable per cabinet at the correct height configuration. For replacement and service work, the 3-1/2 in cable length is the identifier for the 3-high version; verify the drawer count on the existing cabinet before pulling the replacement SKU.
It is made for KV 8500T, 8505T, 8520T, and 8525T lateral file drawer systems only. The Interlok program is series-specific, so cables from other programs or other brands will not fit or function correctly in these slide systems.
No. The cable is sized for the 3-high stack. Two-drawer and four-drawer lateral file configurations use different cables matched to those heights. Ordering the wrong height cable means the interlock sequence will not work as intended.
It is a mechanical interlock, not a lock. The cable links the drawers so that once one drawer is open, the others cannot extend. This prevents the simultaneous-extension scenario that causes lateral file tip-overs. It does not lock drawers closed; any drawer can be opened, but only one at a time.
The source data identifies this as the cable accessory for the 8500-series Interlok system. Whether additional Interlok hardware — brackets, anchors, or linkages — is already present in the slide set or must be ordered separately depends on the specific slide configuration. Refer to the KV 8500-series installation documentation for the complete Interlok component list.
A lateral file without an anti-tilt interlock is a tip hazard waiting for a distracted moment. This KV Interlok cable closes that gap for 3-high configurations, keeping a fully loaded cabinet stable no matter how the drawers are used — and keeping the install code-compliant in environments where anti-tilt is required.
