Fulterer 40" Full Extension Hold-In/Hold-Out Ball Bearing Drawer Slides, Unhanded Side Mount Zinc - 5376

Zinc-Finished Ball Bearing Drawer Slides Built for Heavy Industrial and Shop Use

This is a 40 inch full-extension side-mount ball bearing drawer slide from Fulterer, rated 550 lb per pair, with a hold-in/hold-out detent that keeps the drawer firmly closed or positively open on demand. The zinc finish provides indoor corrosion resistance suited to shop environments, tool storage, and industrial cabinet work where appearance is secondary to performance.

Key Features

• 550 lb weight capacity per pair — handles the heaviest shop and industrial storage loads well beyond the standard 100 lb cabinet class.
• Full extension — the entire drawer travels clear of the cabinet opening, giving complete access to the back of even a 40 inch deep drawer.
• Hold-in/hold-out detent — a mechanical catch holds the drawer firmly shut until pulled, and holds it fully open until pushed closed, hands-free in both positions.
• Steel ball bearings in full-length raceways — smooth, controlled telescopic travel under extreme load without racking or side play.
• Non-handed design — both slides in the pair are identical, so there is no left/right sorting during installation.
• 3/4 inch side clearance per side — sized for the heavier slide profile; size the drawer box accordingly.

Where This Slide Earns Its Place

A 550 lb rated slide in a 40 inch length is not a kitchen cabinet product. It belongs in tool storage cabinets, machinist chests, workshop carts, fleet-service drawers, and industrial casework where the drawer is expected to carry dense loads every working day. The hold-in detent is the feature that prevents an accidentally pushed drawer from rolling back open in a busy shop, and the hold-out detent keeps it extended while both hands are occupied loading or unloading heavy stock. For drawers running under worktops or in cabinets where a 40 inch depth is standard, full extension at this load class is the combination that makes the rear of the drawer genuinely accessible.

Materials and Finish

The slide members are cold-formed steel, finished in zinc for reliable indoor corrosion protection. Zinc is the working standard for high-load side-mount ball bearing slides: it handles the humidity and grime of a production shop environment without the cost premium of a decorative finish. At 40 inches and 550 lb rated capacity, these slides carry a substantially heavier steel section than the standard cabinet class, which is visible in the profile and weight of the product. This is a functional, purpose-built finish for environments where the slide stays out of sight beside the drawer box.

Specifying the Right Application

This slide is the right choice when two conditions are both true: the load is too heavy for standard or mid-duty ball bearing slides, and the cabinet depth calls for a 40 inch slide. Cabinet shops building custom tool storage, contractors fitting out service trucks with fixed cabinetry, and facilities teams specifying industrial parts drawers are the buyers this product is sized for. Because the slide requires 3/4 inch of clearance per side — more than the 1/2 inch standard on lighter slides — confirm the drawer box width before building. In face-frame cabinets, rear mounting support is required; brackets are series-specific and sold separately.

The Right Slide When the Load Is Serious

When the drawer carries real industrial weight and needs to stay put at both ends of its travel, this 40 inch 550 lb rated slide with hold-in/hold-out detents delivers the capacity and control the job demands.
