Zinc Finish And 500 lb Capacity In a 44 Inch Full-Extension Side Mount Slide

The Knape and Vogt 8900 Series is a 44 inch full-extension side-mount ball bearing drawer slide rated 500 lb per pair, built for industrial, commercial, and heavy shop drawers where a standard cabinet slide falls well short of the load. The zinc finish is a proven workhorse coating that protects the steel members through years of demanding indoor service.

Key Features

• 500 lb weight capacity per pair — engineered for drawers that carry real industrial loads, far beyond the standard 100 lb cabinet class.
• Full extension — the drawer travels its full length out of the cabinet so the entire contents are reachable from the front.
• 44 inch slide length — sized for deep drawers in workbenches, industrial cabinets, server racks, and heavy storage applications.
• 3/4 inch side clearance per side — wider than the standard 1/2 inch cabinet-slide spec; build the drawer box accordingly.
• Non-handed design — both slides in the pair are identical, no left/right sorting on the bench or at the job site.
• Bulk-Pack packaging — sold in a bulk carton for shops and contractors ordering in volume rather than one pair at a time.

Where a 500 lb Slide Belongs

Most side-mount ball bearing slides top out in the 100 to 150 lb class, which covers kitchen and office drawers comfortably. The 8900 series exists for the applications that exceed that ceiling: a mechanics tool chest with deep sockets and heavy wrenches, a server rack pull-out carrying populated blade units, a commercial kitchen prep-table drawer loaded with hotel pans, or a shop storage cabinet built to hold plate steel stock. At 44 inches, this slide also covers the extra depth of industrial cabinets and workbenches that standard 24 or 26 inch kitchen slides were never designed to reach. The standard motion means no closing mechanism competes with the load — the drawer stays exactly where it is left, which is the right behavior for a work surface that needs to stay open.

Steel Construction and Zinc Finish

The slide members are cold-formed steel, the structural choice for slides that carry loads in the hundreds of pounds. Zinc plating over steel delivers reliable indoor corrosion resistance in shop and commercial environments. This is the same functional protective finish found across the heavy-duty side-mount segment — practical, durable, and low-profile once the drawer is closed. Zinc is not a decorative finish and is not rated for wet or outdoor environments; this slide is for dry, indoor applications.

Who Specifies the 8900 Series

Cabinet shops building custom shop furniture, contractors fitting out commercial kitchens, and facility managers equipping maintenance and storage rooms all reach for a slide like the 8900 when the load spec rules out the standard-duty class. The Bulk-Pack format suits any operation ordering slides in quantity for a run of identical cabinets or a large installation. At 3/4 inch clearance per side, the drawer box must be built 1-1/2 inches narrower than the cabinet opening — measure before cutting. In face-frame cabinets, rear mounting brackets are required to support the back end of the slide; brackets are sold separately and are series-specific.

Built for the Loads That Standard Slides Cannot Handle

When the drawer spec calls for 500 lb capacity and 44 inches of depth, the 8900 series delivers full extension and zinc-finished steel construction in the volume format shops and contractors need to get the job done.
