The Fulterer 5380 is a 48 inch full-extension side-mount ball bearing drawer slide rated 550 lb per pair, finished in zinc and equipped with both hold-in and hold-out detents for drawers that must stay put in demanding work environments.
At 48 inches and 550 lb rated capacity, this slide is built for applications that overwhelm standard cabinet hardware. Think machine shop tool drawers loaded with precision instruments, industrial workbench pull-outs carrying heavy fixtures, or equipment enclosures where a loaded drawer must stay fully open while a technician works inside. The hold-out detent is the feature that makes hands-free work possible: the drawer locks at full open and releases with a deliberate push, not an accidental nudge. The hold-in detent on the closed end keeps a loaded drawer from rolling open on an uneven floor or when a wheeled cabinet is moved. Together, the two detents turn this into a slide that actively controls the drawer rather than simply riding under it.
The slide members are cold-formed steel with a zinc electroplate finish — the working standard for industrial side-mount slides. Zinc provides reliable indoor corrosion resistance on a slide that will be mostly hidden beside the drawer box in service. It is a functional, durable finish suited to shop floors, equipment bays, and server rooms: not a decorative choice, but an honest one that does the job without adding unnecessary cost. The 3/4 inch side clearance requirement is wider than the 1/2 inch standard for lighter cabinet slides, so plan the drawer box width accordingly before cutting.
Cabinet shops fitting out industrial workstations, tool crib drawers, or heavy-duty mobile carts will find the 5380 in the right capacity range for loads that standard 100 lb or 150 lb slides cannot safely carry. It also fits commercial equipment enclosures and rack systems where long travel at high load is a daily requirement, not an edge case. The non-handed design keeps inventory simple — one part number covers both sides of every drawer. Sold as a pair; order one pair per drawer.
550 lb is the per-pair rating — the working capacity of one complete set of two slides installed on a single drawer.
Hold-in keeps the drawer closed and prevents it from bouncing back open when pushed shut firmly. Hold-out catches the drawer at the fully open position and holds it there until you push it closed intentionally. There is no spring assist and no damping — both are mechanical detents, not soft-close or self-close features.
The heavier steel profile required for a 550 lb rating takes up more lateral space than a standard cabinet slide. Build the drawer box 1-1/2 inches narrower than the cabinet opening to leave the required 3/4 inch clearance on each side.
Side-mount slides in face-frame cabinets need rear support at the back of the slide. Add the appropriate rear mounting brackets for your installation — brackets are series-specific and sold separately.
Yes. Full extension means the drawer member travels the full slide length, bringing the whole drawer clear of the cabinet opening. The 48 inch measurement is the closed slide length, not a travel distance separate from it.
A 48 inch, 550 lb slide with dual detents is a precision tool for serious industrial and commercial drawers — reliable where lighter hardware fails, and designed so the drawer does exactly what the operator needs it to do.
