Fulterer 16" Full Extension Ball Bearing Drawer Slides, Unhanded Side Mount Zinc - 5504

Fulterer Heavy-Duty Ball Bearing Slide Built for 550 lb Loads

This is a 16 inch full-extension side-mount ball bearing drawer slide from Fulterer, rated 550 lb per pair and finished in zinc. It is built for industrial, shop, and commercial drawers where standard-class slides fall short by a wide margin.

Key Features

• 550 lb weight capacity per pair — a heavy-duty rating that handles tool chests, parts drawers, and loaded service drawers that would overwhelm a standard cabinet slide.
• Full extension — the drawer member travels the full slide length, bringing the entire drawer clear of the cabinet face for complete access to the back.
• Steel ball bearings in full-length raceways — smooth, consistent travel under sustained heavy load.
• Non-handed design — both slides in the pair are identical; no left/right sorting required on the bench.
• Zinc finish — electroplated steel for indoor corrosion resistance in demanding shop and industrial environments.
• Standard motion — no soft-close or self-close mechanism; the drawer stays wherever it is left, making this a clean choice for push-to-open retrofits or drawers that need no closing feature.

Where 550 lb Capacity Changes the Outcome

Most residential and light commercial side-mount slides top out at 100 lb per pair. The Fulterer 5504 operates at more than five times that rating, which puts it in a different application class entirely. Think mechanic's service benches, machine shop part storage, heavy filing systems, retail fixture drawers stacked with product, and cabinetry supporting tools or equipment that simply cannot be trusted to a standard-duty slide. Full extension means the rear of the drawer is reachable without reaching over the cabinet face, which matters when the drawer is loaded and access to the back row is part of the workflow. At 16 inches, this slide suits shallower utility cabinets, rolling tool carts, and base units where interior depth is limited but the load is not.

Steel Construction and Zinc Finish

The slide is cold-formed steel with ball bearings running in formed steel raceways — the same construction principle as lighter cabinet slides, scaled for the load class. The zinc finish provides the standard level of indoor corrosion protection for steel hardware: adequate for shop, garage, and commercial interior environments. Zinc finish is a functional, not decorative, choice — the slide sits beside the open drawer box and is not meant to be seen. It is an indoor finish; if the application involves persistent moisture, condensation, or washdown, a stainless or coated alternative is the correct specification.

Who This Slide Is For

The 5504 is the right choice for builders and fabricators who are putting heavy drawers into demanding service. Cabinet shops building shop furniture, tool storage, and utility carts will find the load rating relevant, as will contractors sourcing slides for commercial millwork that carries real weight. The non-handed design keeps the installation straightforward and reduces the chance of a mis-order when equipping multiple drawers at once. Pair one slide on each side of the drawer box with 1/2 inch of side clearance per side, and the drawer is supported for the full load class. For face-frame cabinet installations, rear mounting bracket support is required at the back of the slide; verify bracket compatibility with the Fulterer series before ordering.

The Right Slide When the Load Is Serious

When the drawer carries real weight and standard-duty hardware is not enough, the Fulterer 5504 delivers full extension and a 550 lb pair rating in a zinc-finished steel package sized for 16 inch cabinet depths.
