This is a 28 inch full-extension side-mount ball bearing drawer slide from Knape and Vogt's 8900 series, rated 500 lb per pair and finished in zinc. It is the slide to reach for when a standard 100 lb cabinet slide falls well short of what the application demands.
A loaded mechanic's top box, a deep shop drawer full of hand tools, a heavy-duty storage cabinet in a commercial space — these are applications where a standard kitchen-class slide is simply undersized. The 8900 series steps into that gap with a 500 lb per-pair rating that covers loads most side-mount slides never see. Full extension means the drawer travels its full length clear of the face, so the contents at the rear are as reachable as the contents at the front. The 28 inch length suits deep base cabinets, workbenches, and full-depth storage units where shorter slides leave capacity on the table.
Zinc plating over cold-rolled steel is the workhorse finish in this segment — not decorative, not stainless, but durable and corrosion-resistant through years of indoor service. On a slide that lives inside a shop cabinet or utility unit, the zinc finish protects the steel members through heat, humidity, and regular use without adding unnecessary cost. This is an indoor finish; for washdown, marine, or wet environments, specify a stainless option instead.
Cabinet shops building heavy-duty base units, contractors fitting out commercial and institutional spaces, and facility maintenance teams replacing slides in loaded storage cabinets all find the 8900 series useful. The bulk-pack format supports multi-drawer projects without reordering delays. Note that this slide requires 3/4 inch of side clearance per side — wider than the 1/2 inch standard on most kitchen-class slides — so the drawer box needs to be sized accordingly before cutting. In face-frame cabinet installations, rear mounting brackets are required to support the slide's back end; those brackets are sold separately and are series-specific to the 8900 line.
Per pair. Both slides together carry 500 lb. Do not double the number by counting each slide separately.
This slide requires 3/4 inch of clearance per side — more than the 1/2 inch used by standard kitchen-class slides. Build the drawer box 1-1/2 inches narrower than the cabinet opening to account for both sides.
Neither. The 8900 series uses standard motion — no closing mechanism of any kind. The drawer rolls freely and stays wherever it is left.
No. The slide is non-handed, so both pieces in a pair are identical and fit either side of the drawer.
Yes, but rear mounting brackets are required in face-frame installations to support the back of the slide. Brackets are sold separately and must be matched to the 8900 series specifically.
When the drawer is going to carry genuine weight day after day, the 8900 series delivers full extension and a 500 lb per-pair rating in a zinc-finished steel slide that installs without handed sorting and ships in bulk quantity for multi-drawer projects.
