The Knape and Vogt 6500 Series is a 12 inch full-extension side-mount ball bearing drawer slide rated 125 lb per pair, sized for file drawers and heavy-duty storage applications where a standard 100 lb cabinet slide falls short.
A loaded file drawer — letter-size hanging files, binders, and reams of paper — routinely pushes or exceeds 100 lb. The 6500 Series is rated at 125 lb per pair, which puts a standard file draw well within the operating range and leaves margin for heavier loads. Full extension means the entire drawer comes out past the cabinet face, so the rearmost hanging files are reachable without digging. At 12 inches, this slide length suits shallow file pedestals and compact under-desk storage units where a longer slide would not fit the cabinet's interior depth.
The 6500 Series is cold-formed steel with a zinc finish. Zinc is the working standard for side-mount ball bearing slides: it resists corrosion in dry indoor environments and holds up through the open-close cycle count of an active office drawer. This is a functional, mostly hidden finish — the slides sit beside the drawer box and are not visible through the drawer front.
Cabinet shops building file pedestals and lateral file units will find the 125 lb rating and full extension a natural spec for that application. Office furniture manufacturers and commercial outfitters running production will appreciate the Bulk-Pack format, which minimizes handling and keeps the bench supplied. Contractors retrofitting file storage into face-frame casework should plan for rear mounting brackets, sold separately, to support the back end of the slide in that construction style.
No. 12 inches is the closed length of the slide. Because this is a full-extension slide, the drawer member travels approximately its full length, bringing the entire drawer box out to the cabinet face — but slide length and travel are two separate facts.
The 6500 Series is rated 125 lb per pair, putting it above the standard 100 lb class. That extra capacity is the right margin for a file drawer carrying a full load of hanging folders or binders.
No. The slide is non-handed, so both pieces in a pair are identical. Order one pair per drawer.
Standard motion means no closing mechanism — no soft-close damper, no self-close spring, and no hold-in detent. The drawer stays wherever it is left and requires a deliberate push to close.
It can, but face-frame construction sets the cabinet side back from the face, so the slide needs rear support. Add the appropriate rear mounting brackets for this series — they are sold separately and are series-specific.
When the drawer carries real weight and needs to open completely, the 6500 Series delivers a 125 lb rating and full extension in a zinc-finished, non-handed format built for production volume.
