Fulterer 48" Side Mount Full Extension 550 lb Ball Bearing Drawer Slide, Zinc, 5520

Fulterer Heavy-Duty Ball Bearing Slides Built for Industrial and Workshop Loads

This is a 48 inch full-extension side-mount ball bearing drawer slide from Fulterer, rated 550 lb per pair, finished in zinc, and designed for the deep, heavily loaded drawers found in shop carts, industrial workstations, and custom storage builds where standard cabinet-class slides are simply not enough.

Key Features

• 550 lb load rating per pair — built for tool drawers, parts storage, and industrial carts that far exceed the standard 100 lb cabinet class.
• 48 inch full extension — the drawer clears the cabinet face completely, putting the full depth of a deep drawer in reach.
• Steel ball bearings in full-length raceways — smooth, controlled travel under heavy load across the entire 48 inch length.
• Non-handed design — both slides in the pair are identical, so there is no left or right to sort on the bench.
• Zinc finish — electroplated steel provides corrosion resistance suited to dry indoor environments including shops, garages, and utility rooms.
• Standard motion — no closing mechanism, so the drawer stays exactly where it is left, open or closed.

Where a 550 lb, 48 Inch Slide Earns Its Keep

A 48 inch slide is not a kitchen drawer upgrade — it belongs in builds where depth and weight are both serious considerations. Shop tool carts with heavy wrench and socket sets, parts drawers on assembly benches, archival flat-file storage, server infrastructure pulls, and utility storage on industrial carts are all natural fits. At 550 lb per pair, this slide handles loads that would buckle or bind a standard-class slide within a few cycles. The full-extension design means the back of a 4-foot-deep drawer is as reachable as the front, which matters when the contents at the rear are part of the workflow.

Zinc Finish on a Working Slide

The zinc electroplate on the steel members is the segment's standard corrosion-resistant finish — practical, durable, and at home in shops, garages, and utility installations where a decorative finish would be out of place. Zinc is not a stainless or marine-grade coating; keep this slide indoors and away from wet or washdown environments. The finish blends quietly with painted metal cabinets, steel drawer boxes, and shop equipment without demanding attention.

Matching the Slide to the Build

Side-mount ball bearing slides at this load class and length require careful drawer box construction. Each slide mounts to the side of the drawer box and the cabinet interior, with 1/2 inch of side clearance per side — build the drawer box 1 inch narrower than the cabinet opening to accommodate both slides. In face-frame cabinets, rear mounting support is needed at the back of the slide; confirm the appropriate rear brackets for this series before the build. This slide ships as a standard-motion pair with no self-close, soft-close, or detent mechanism, so the installation does not need to account for a closing feature. Order one pair per drawer.

The Right Slide for Deep, Heavy Work

When the build calls for a 48 inch drawer that carries real weight and needs to open completely, this slide delivers the load rating, the extension, and the no-nonsense zinc finish to get the job done in a shop or industrial setting.
