This is the left-hand cabinet member from Knape and Vogt's 8505 series: a 24 inch side-mount ball bearing file drawer slide rated in the 150 lb class per pair, with 1 inch of over-travel beyond full extension and a hold-in anti-rebound detent. It is the cabinet-side component only — pair it with the matching right-hand cabinet member and both drawer members to complete a working set.
A standard full-extension slide brings the drawer face to the cabinet opening and stops. The 8505 carries the drawer 1 inch farther, which matters when the drawer sits under a countertop overhang or behind a face frame with any depth. That extra inch is the difference between reaching the back row of hanging folders comfortably and fishing for them. The hold-in anti-rebound detent addresses the other common file drawer annoyance: a heavy, well-loaded drawer that rebounds open after a firm close stays put instead.
The cabinet member is cold-formed steel with a zinc finish. Zinc plating is the working standard for side-mount ball bearing slides — it resists indoor corrosion through years of daily cycling without adding a decorative premium. The slide profile is 3.79 inches tall including the quick-disconnect rail, which sits higher than a standard cabinet slide and is sized for the wider drawer boxes common in lateral file and heavy storage applications.
Cabinet shops and commercial installers building lateral file units, paper-storage drawers, or heavy pull-out shelves under overhanging worktops are the core buyers. The 150 lb class covers a lateral file drawer loaded with folders; the over-travel handles the architectural reality of most worktop installations. Face-frame cabinetry is a common application here: the 8505 installs on the 32mm hole pattern, and face-frame installs require rear mounting brackets at the back of the cabinet, sold separately. The maximum recommended drawer width for the 8505 is 30 inches. This Q-Pack is packaged for shop use rather than retail display.
This is the left-hand cabinet member only — the component that mounts to the left side of the cabinet interior. A complete drawer installation requires the right-hand cabinet member plus two drawer members. Order each component separately or confirm that the family SKUs cover your full set.
The slide is 24 inches long (closed length). It is full extension plus 1 inch of over-travel, so the drawer member extends the full slide length and then continues 1 inch beyond, carrying the drawer past the cabinet face and any countertop overhang above it.
No. The hold-in anti-rebound detent is a mechanical catch: it keeps the drawer closed and stops it from bouncing back open, but it does not pull the drawer shut and it does not slow or damp the closing motion. This is a standard-motion slide with a stay-closed detent.
Yes, with the appropriate rear mounting brackets. Face-frame construction sets the cabinet side back from the opening, so the slide's back end needs support. The brackets are series-specific and sold separately — confirm the 8505-compatible bracket SKU before ordering.
The slide requires 1/2 inch of side clearance per side, so the drawer box should be built 1 inch narrower than the cabinet interior opening.
When the drawer carries a real paper load and sits under an overhang, the 8505's over-travel and 150 lb class rating handle both constraints — and the hold-in detent keeps it where it belongs when closed.
