This 16 inch side-mount ball bearing drawer slide from Knape and Vogt's 8505 series combines a 1-inch over-travel action with a 150 lb class load rating, making it the right choice for file drawers that sit beneath worktop overhangs or behind deep face frames and carry a serious paper load.
A plain full-extension slide opens the drawer to the cabinet face. The 8505 goes one inch further. Under a countertop overhang — typical in kitchen islands, office credenzas, and shop workbenches — that extra inch is what separates the rear hanging files from a drawer you have to dig through. The same benefit applies in face-frame cabinets where a deep frame leaves the drawer opening set back from the front edge. At 16 inches, this slide suits shallower file pedestals and under-desk units where a longer slide would not fit the cabinet depth.
Steel construction with a zinc finish keeps the slides working in dry, indoor environments through years of daily use. The 150 lb class rating is per pair, appropriate for a lateral file drawer or a storage drawer carrying tools, binders, or heavy goods well beyond what a standard kitchen cabinet slide handles. Ball bearings run in formed steel raceways for consistent, smooth pull across the full load range. The zinc finish is a functional indoor coating, not a decorative one — it will spend most of its life beside the drawer box, out of sight.
Cabinet shops building file pedestals, office credenzas, and under-desk storage will find this slide fills the gap between a 100 lb kitchen slide and a full-depth file cabinet runner. Contractors fitting office or shop furniture beneath worktop overhangs get the over-travel without stepping up to a heavier slide class they do not need. Homeowners building a home-office built-in or a workshop cabinet under a bench top will appreciate that both slides in the pair are identical — no handed sets to keep track of. The bulk-pack format suits shops ordering a quantity for a multi-drawer project rather than a single retrofit. This is an indoor slide; it is not rated for wet or exterior environments.
Yes, with a distinction. The slide's closed length is 16 inches. Over-travel carries the drawer member one inch past that nominal length, so the drawer travels further than the slide itself is long — past the cabinet face and clear of the overhang. Slide length and drawer travel are two separate specs.
No. The hold-in anti-rebound detent is a mechanical catch that keeps the drawer closed and stops it from bouncing back open when pushed shut firmly. There is no damper and no spring assist — the drawer stays where it is left and releases with a normal pull. If you need damped closing, look at soft-close versions in this series.
The 8505 requires 1/2 inch of clearance on each side between the drawer box and the cabinet interior — build the drawer box 1 inch narrower than the cabinet opening. The tolerance is +0.03/-0 inch, so the clearance can run slightly over 1/2 inch but not under.
Yes, with rear support. Side-mount slides need backing at the rear of the cabinet in face-frame construction because the side panel is set back from the front frame. Add the matching KV rear mounting brackets — sold separately and series-specific — to support the back end of the slide properly.
Bulk-pack is the trade-quantity format, packaged loose in a carton rather than in a retail polybag. Confirm the sold-as unit at the time of ordering — whether the count is per pair or per slide — so you order the right quantity for your drawer count.
When the cabinet sits under an overhang and the drawer carries real weight, the 8505 series gives you the extra inch of travel and the file-class load rating in one non-handed, zinc-finished package — without overbuilding for jobs that do not need it.
