Zinc-Finished File-Class Drawer Slide For Heavy Storage and Shop Drawers
This is a 14 inch full-extension side-mount ball bearing drawer slide from Knape and Vogt's 8500 series, rated 150 lb per pair in a bright zinc finish. It is built for file drawers, shop drawers, and storage cabinets that push past the 100 lb limit of standard kitchen slides.
Key Features
150 lb load class per pair — steps up from the standard 100 lb cabinet class for drawers carrying files, hardware, or heavy shop stock.
Full extension — the entire drawer clears the cabinet opening so the back of the box is reachable without digging.
Hold-in anti-rebound detent — a mechanical catch keeps the drawer closed and stops it from bouncing back open when shut firmly.
Steel ball bearings in progressive-movement raceways — smooth, even travel under a fully loaded drawer.
Non-handed design — the same slide fits either side of the drawer, so there is no left/right sorting at the bench.
Zinc finish — electroplated steel construction provides reliable indoor corrosion resistance across years of regular use.
Where the 150 lb Rating Makes the Difference
A standard 100 lb cabinet slide is correctly sized for a kitchen drawer full of pots and pans. It is not correctly sized for a lateral file drawer loaded with hanging folders, a shop drawer carrying heavy tooling, or a utility cabinet holding hardware bins. The KV 8500 series occupies a different duty class: 150 lb per pair, with progressive ball-bearing movement that handles the uneven loading common to file and work drawers. The hold-in anti-rebound detent matters here too — a loaded drawer that bounces back open every time it is pushed shut becomes a real annoyance in a busy workspace. This slide stays put.
Zinc Finish and Steel Construction
The bright zinc electroplate over steel is the segment's working standard for indoor slide hardware. It protects the steel members against the humidity and seasonal variation of a shop or office environment without adding bulk. Zinc is a functional finish; the slide sits beside the open drawer box and is not a decorative element. It holds up through repeated daily cycles without flaking, peeling, or binding. For outdoor or high-moisture environments, zinc plating is not a corrosion-resistant substitute for stainless — this slide is for indoor work.
Right Fit for File Drawers and Heavy-Duty Shop Cabinets
The KV 8500 series is designed around the demands of file and lateral drawers: a 14 inch length suits shallow file cabinets and compact shop drawers where a longer slide would not fit the cabinet depth. The 1/2 inch side clearance requirement matches the standard ball-bearing side-mount format, so the drawer box is built 1 inch narrower than the cabinet opening. The non-handed design keeps the order simple — one part number covers both sides of the drawer. This SKU ships in a bulk pack, which makes it a practical choice for cabinet shops or contractors outfitting multiple drawers at once. In face-frame cabinets, rear mounting brackets are required to support the back of the slide; those brackets are series-specific and sold separately.
Common Questions
Does full extension mean the slide opens 14 inches?
No. 14 inches is the closed length of the slide. Full extension means the drawer member travels approximately the full slide length, bringing the entire drawer box clear of the cabinet face — but slide length and travel distance are two separate specs.
Is this the same as a soft-close slide?
No. The hold-in anti-rebound detent is a mechanical catch that keeps the drawer closed and prevents it from rebounding after a firm push. There is no damper and no spring assist — the drawer stays where you leave it but does not close on its own.
Do I need to order a left-hand and a right-hand slide?
No. The 8500 series is non-handed, so both slides in a pair are identical. Order one pair per drawer.
Do face-frame cabinets need extra hardware?
Yes. In face-frame construction the slide needs rear support. Add the matching KV rear mounting brackets, which are series-specific and sold separately from the slides.
What does bulk pack mean for this SKU?
Bulk pack means the slides are packed loose in a carton rather than individually bagged or boxed. It is the standard trade format for shops and contractors ordering in volume rather than single-pair retail quantities.
Heavy-Load Drawers That Stay Shut and Open Fully
When the job calls for a drawer that handles real weight, clears the cabinet completely at full open, and stays closed without bouncing back, the KV 8500 series in zinc delivers exactly that — in a non-handed format that keeps ordering and installation straightforward.
