This is a 50 inch full-extension side-mount ball bearing drawer slide from Fulterer, rated 550 lb per pair, with a zinc finish and combined hold-in/hold-out detents that keep the drawer firmly in place at both the closed and fully open positions.
At 550 lb per pair, this slide belongs in drawers where the contents themselves are the challenge: fully loaded tool chests, industrial parts drawers, heavy machine shop trays, and commercial storage applications where a standard 100 lb or even 150 lb cabinet slide would be undersized. The full-extension travel means a 50 inch drawer opens all the way past the cabinet face, so nothing at the back requires digging. The hold-in detent prevents a loaded drawer from drifting or bouncing back open after being pushed shut — a real concern when a heavy drawer is closed with any force. The hold-out detent keeps the drawer at full open hands-free, which matters on a work surface or service tray where both hands are occupied.
The slide members are cold-formed steel with a zinc finish applied for indoor corrosion resistance. Zinc is the workhorse finish for heavy-duty side-mount slides — it protects against the moisture and handling typical of a shop or storage environment without the cost of stainless. These slides are designed for dry indoor applications. The non-handed construction means both slides are identical, which simplifies receiving, storage, and installation on high-volume jobs.
The 50 inch nominal length suits very deep cabinets and specialty shop furniture — measure the cabinet's interior depth before ordering to confirm fit. Unlike standard cabinet-class slides that require 1/2 inch of side clearance per side, this heavy-duty slide requires 3/4 inch of clearance per side, so the drawer box must be built 1-1/2 inches narrower than the cabinet opening. In face-frame cabinets, rear support at the back of the slide is required; confirm bracket compatibility with Fulterer before ordering. This slide is sold as a pair.
The hold-in detent is a mechanical catch that keeps the drawer closed and prevents it from bouncing back open after being pushed shut. The hold-out detent holds the drawer in the fully open position until you intentionally push it closed. Neither feature locks the drawer — both release with a normal pull or push. There is no spring assist and no damper; this is not a self-close or soft-close slide.
The heavier steel construction of a 550 lb slide requires a wider profile than a standard cabinet-class slide, which pushes the required side clearance from 1/2 inch to 3/4 inch per side. Build the drawer box 1-1/2 inches narrower than the cabinet opening — not 1 inch — to get the fit right.
No. 50 inches is the closed length of the slide. Because this is a full-extension slide, the drawer travels approximately the full slide length, bringing the entire drawer clear of the cabinet face — but slide length and travel are two separate specs. Confirm the cabinet's interior depth accommodates the 50 inch slide before ordering.
No. The slide is non-handed, so both pieces in the pair are identical. Order one pair per drawer.
The zinc finish provides corrosion resistance for indoor use. These slides are for dry, indoor applications — not for exterior, marine, or washdown environments.
When the drawer is deep, the load is real, and it needs to stay exactly where you put it, the Fulterer 5381 delivers: 550 lb capacity, full extension to the back of a 50 inch drawer, and detents that hold in both directions.
