16 Inch Over-Travel File Drawer Slide for Heavy Storage Under Overhangs

The Knape and Vogt 8525 series is a 16 inch side-mount ball bearing file drawer slide rated 175 lb per pair, with 1-1/4 inch over-travel and a hold-in anti-rebound detent — built for file and heavy storage drawers that sit under countertop overhangs or behind deep face frames.

Key Features

• 175 lb weight capacity per pair — steps past the standard 100 lb cabinet class for genuinely loaded file and storage drawers.
• 1-1/4 inch over-travel — the drawer member extends 1-1/4 inches beyond full extension, pushing the drawer past a countertop overhang or deep face frame so rear contents are reachable.
• Hold-in anti-rebound detent — a mechanical catch keeps the drawer firmly closed and stops it from bouncing back open when shut with force.
• Steel ball bearings in full-length raceways — smooth, consistent travel on a loaded drawer throughout the slide's service life.
• Non-handed design — both slides in the pair are identical, fitting either side of the drawer without sorting on the bench.
• Zinc finish on cold-formed steel — standard indoor corrosion resistance for a side-mount slide that lives beside the open drawer box.

Where the Over-Travel Makes the Difference

A standard full-extension slide brings the drawer face even with the cabinet front and stops. Under a countertop overhang or inside a deep face-frame opening, that means the back of the drawer is still blocked. The 8525's 1-1/4 inch over-travel carries the drawer past that point — a shallow file drawer under a kitchen island or a utility drawer behind a thick face frame opens completely rather than leaving rear contents out of reach. Pair that with the 175 lb rating and the hold-in detent, and this slide handles a loaded drawer in a demanding cabinet position without drama.

Materials and Finish

The 8525 series is built from cold-formed steel with a zinc electroplate finish. Zinc is the working standard for side-mount ball bearing slides: functional, durable indoors, and mostly hidden beside the drawer box once installed. This is not a decorative finish, and it is not rated for wet or exterior environments. The poly-pack includes mounting hardware.

Who Reaches for the 8525

Cabinet installers fitting file drawers under kitchen islands, designers specifying shallow utility drawers behind deep face frames, and shop owners building tool storage under workbench overhangs all run into the same problem: full extension is not enough travel. The 8525 solves it with over-travel at a 175 lb class rating that covers a drawer loaded with lateral files or heavy tools. At 16 inches, it fits shallower cabinet runs where longer file slides will not land. Face-frame installs need rear support at the back of the slide — add the matching KV rear mounting brackets, sold separately, or use a face-frame-specific mounting approach for this series.

The Right Slide for a Tight Cabinet Position

When 16 inches of depth, a 175 lb load, and the need to clear an overhang all land on the same drawer, the 8525 series is sized for exactly that combination — over-travel, heavy-duty capacity, and a stay-closed detent in one compact slide.
