Knape and Vogt 8505 Left-Hand Cabinet Member For Heavy File and Storage Drawers

This is the left-hand cabinet member from Knape and Vogt's 8505 series — an 18 inch over-travel, 150 lb class ball bearing file drawer slide component, side-mounted with a zinc finish and a hold-in anti-rebound detent. Order this part when you are replacing the left-side cabinet rail in a 8505 series installation or building out a new run of file or heavy storage drawers that requires the over-travel action the full-extension 8500 does not provide.

Key Features

• 150 lb load class per pair — sized for file and lateral drawers that push past the limit of standard 100 lb cabinet slides.
• 1 inch over-travel — the drawer member travels 1 inch past full extension, pulling the drawer clear of countertop overhangs and deep face frames.
• Hold-in anti-rebound detent — a mechanical catch keeps the drawer closed after a firm push and stops it from bouncing back open.
• Ball bearing movement on steel raceways — smooth, consistent travel even under a full paper load in a wide lateral drawer.
• Left-hand orientation, 1/2 inch side clearance — fits the left side of the cabinet; build the drawer box 1 inch narrower than the opening to accommodate both slides.
• Q-Pack format — packaged as a trade quantity for shops outfitting multiple file bays in one order.

Where the Over-Travel Matters Most

A standard full-extension slide brings the drawer to the cabinet face — nothing more. In a run of lateral files tucked under a worktop overhang, or in a face-frame cabinet with a deep stile, that last inch disappears under the lip and the rearmost hanging folders stay out of reach. The 8505's 1 inch of over-travel pushes the drawer past that obstruction so the full depth of the file is accessible. The same extra travel benefits deep shop drawers under bench overhangs where the back inch of the drawer is otherwise a blind spot. The hold-in anti-rebound detent pairs naturally with this application: a loaded file drawer pushed shut firmly stays shut rather than rebounding open.

Steel, Zinc, and the 8505 Build

Steel members carry a zinc finish — the standard indoor corrosion protection for ball bearing file slides. This is a functional, working finish; zinc is not stainless and this slide is for dry, interior installations. The 8505 series profile is taller than a standard cabinet slide and includes the quick-disconnect rail that allows the drawer to lift free without tools once extended. Progressive ball bearing movement distributes load evenly across the travel, which matters at the 150 lb class with a wide lateral drawer that can flex under a full paper load.

Specifying the Left-Hand Member Correctly

The 8505 series sells cabinet members and drawer members as individual components, and the cabinet members are handed. This listing is the left-hand cabinet member only — it mounts to the left interior side of the cabinet as viewed from the front. A complete drawer installation requires one left-hand cabinet member, one right-hand cabinet member, and two drawer members. If you are replacing a single failed rail, confirm the side before ordering. Rear mounting brackets are required in face-frame cabinets and are sold separately; confirm bracket compatibility within the 8505 series before ordering. KV rates this series for drawers up to 30 inches wide in the over-travel configuration.

Common Questions

The Right Component for a Demanding File Drawer

When a lateral file sits under a worktop and a standard full-extension slide leaves the back folders unreachable, this left-hand 8505 cabinet member — with its 1 inch of over-travel and 150 lb class rating — is the part that closes that gap.
