This 22 inch side-mount ball bearing file drawer slide from Knape & Vogt's 8505 series pairs a 150 lb class load rating with 1 inch of over-travel, so the drawer clears the cabinet face and keeps going — putting every hanging folder within reach even when the drawer sits under a countertop overhang or behind a deep face frame.
A standard full-extension slide stops at the cabinet face. On a drawer tucked under a 24-inch countertop or behind a thick face frame, that leaves the rear files just out of reach. The 8505's 1 inch of over-travel pushes the drawer box past the face, giving clear access to the back of the drawer without leaning in. Lateral files, office credenzas, and under-worktop storage cabinets are the natural fits. The 150 lb class rating covers a drawer loaded with folders, binders, or heavy tooling — applications where the standard cabinet-slide class runs short.
The slide members are cold-formed steel, finished in zinc for indoor corrosion resistance. Zinc is the working standard for side-mount ball bearing slides in shop and office environments: functional, durable, and mostly hidden alongside the drawer box when the drawer is open. The 3.79 inch profile height accommodates the quick-disconnect rail built into the KV 8500 series, which allows the drawer members to lift free without tools when the drawer is fully extended.
Cabinet shops building file pedestals, credenzas, or lateral file units in office furniture will find the 8505 a reliable workhorse: the 150 lb class covers realistically loaded drawers, and the 1 inch over-travel handles most countertop overhang depths without a custom solution. Installers doing a run of office cabinetry benefit from the Bulk-Pack format, which reduces handling per drawer. The non-handed design cuts install time — one slide orientation fits both sides of every drawer. For face-frame cabinets, add the series-matched KV rear mounting brackets (sold separately) to support the slide's back end.
No. Twenty-two inches is the closed slide length. This is an over-travel slide, so the drawer member travels the full 22 inch length plus 1 additional inch — 23 inches of total travel — past the cabinet face.
It is a mechanical catch that holds the drawer closed after it is pushed shut, preventing it from bouncing back open. There is no spring assist and no damping — the drawer stays put until pulled open intentionally.
The KV 8500 series uses quick-disconnect drawer members: extend the drawer fully and lift it free — no tools required.
Yes, but the slide's back end needs support. Add the matching KV rear mounting brackets for face-frame installation; they are sold separately and are series-specific.
KV recommends a maximum drawer width of 30 inches for the 8505 over-travel model — narrower than the full-extension 8500, which handles up to 36 inches.
When the load is heavy, the drawer sits under an overhang, and the job needs to stay moving, the KV 8505 in 22 inches delivers the capacity, the reach, and the detent to keep file drawers working reliably every day.
