This is a 20 inch side-mount ball bearing drawer slide from Knape and Vogt's 8815 series, rated 190 lb per pair with 1 inch of over-travel that carries the drawer past the cabinet face. The zinc finish and steel construction put this squarely in the workhorse category for shop, utility, and office installations where load capacity and full access both matter.
A standard full-extension slide stops the drawer at the cabinet face. Add a countertop overhang, a deep face frame, or a thick countertop nosing, and the back of the drawer disappears behind the overhang when the drawer is open. The 8815's 1 inch of over-travel pushes the drawer member past the nominal slide length so that rear corner is reachable. This makes it a natural fit for workshop drawers tucked under a benchtop, file drawers under a deep desk return, and utility cabinets where the top rail sits forward of the side panels. The 190 lb rating means a loaded drawer of tools, hardware, or file stock stays well within spec.
The 8815 series is formed from steel and finished in zinc, the standard corrosion-resistant coating for side-mount ball bearing slides used indoors. Zinc is a functional finish: it protects the steel members through years of service in a shop, utility room, or office environment without adding decorative weight to the choice. The slide sits beside the open drawer box and is not concealed, so the zinc finish reads as a clean, neutral metal surface. For installations where the slide will be visible and a darker or lighter finish is preferred, sibling variants in this family are available in other finishes.
The 8815 series suits installers and cabinet shops building heavy-duty drawers in frameless and face-frame cabinets. The non-handed design simplifies ordering for production runs: one SKU covers both sides of every drawer. The 3/4 inch side clearance per side is wider than the 1/2 inch standard found on lighter cabinet slides, so the drawer box must be sized accordingly — plan for 1-1/2 inches of total width reduction from the cabinet opening. In face-frame cabinets, rear mounting brackets are required to support the back of the slide; confirm bracket compatibility with the 8815 series before placing that order. The standard motion means no self-close, no soft-close, and no detent — the drawer stays wherever it is left, which is the right call for utility and shop applications where a closing mechanism would get in the way.
No. Twenty inches is the closed length of the slide. Because this is an over-travel slide, the drawer member extends 1 inch past that length at full open, so the travel exceeds the nominal slide length.
The 8815 series is a heavier-built slide with a taller profile than standard 100 lb cabinet slides. The wider 3/4 inch per-side clearance is part of the manufacturer's specification for this series; build the drawer box 1-1/2 inches narrower than the cabinet opening to get the fit right.
Neither. This is a standard-motion slide with no closing mechanism. The drawer rolls freely and stays wherever it is pushed — open, closed, or anywhere in between.
No. The 8815 is non-handed, so the same slide installs on either side of the drawer.
Bulk-Pack means the slides ship loose in a carton rather than in retail polybags. Check the quantity and sold-as unit shown in the spec block on this page to confirm the number of slides in the pack.
When the drawer sits under an overhang and carries real weight, the 8815 series covers both: 190 lb per pair and 1 inch of over-travel in a zinc-finished steel slide that installs the same way on both sides of the drawer.
