The Fulterer 5379 is a 46 inch full-extension side-mount ball bearing drawer slide rated 550 lb per pair, with a zinc finish and integrated hold-in/hold-out detents that lock the drawer at both the closed and fully open positions.
A 46 inch, 550 lb slide is built for drawers that would destroy a standard kitchen or office slide in short order. Think tool chests with heavy sockets and ratchets, machine shop drawers loaded with fixturing, workbench pull-outs carrying power tools, and industrial storage units in garages or manufacturing facilities. At this length and load class, the hold-in detent is not just a convenience feature — it keeps a loaded drawer from drifting open under vibration or an uneven floor. The hold-out detent is equally practical: when both hands are occupied at the bench, the drawer stays fully open without being propped.
The slides are formed steel with a zinc finish — the working standard for heavy side-mount ball bearing slides in indoor industrial and shop environments. Zinc protects against everyday corrosion and surface wear without the cost of stainless. This is not a decorative finish, and it is not rated for outdoor, wet, or washdown applications. For shop floors, equipment rooms, and indoor storage: zinc is the right call at this load class.
At 46 inches, these slides suit deep drawers in large tool chests, equipment carts, and custom shop cabinetry where a standard 22 or 28 inch slide falls short. The 3/4 inch side clearance per side is wider than the 1/2 inch clearance common in the standard cabinet class — build the drawer box 1-1/2 inches narrower than the cabinet opening to give each slide its full 3/4 inch. The non-handed design means both slides in the pair are identical, so there is no left/right sorting before install. In face-frame cabinets, rear support brackets are required at the back of the slide; confirm bracket compatibility with the Fulterer FR series before ordering.
Hold-in and hold-out are mechanical detents — the hold-in keeps the drawer from bouncing back open after a firm close, and the hold-out keeps the drawer in the fully extended position until pushed shut. Neither feature damps or slows the drawer's travel. This is not a soft-close slide.
550 lb is the rating per pair — both slides together. That covers most heavily loaded shop and industrial drawers, but do not divide the number by two and apply it per slide when sizing for your application.
Yes. Full extension means the drawer member travels the full slide length, bringing the entire drawer out past the cabinet face. The whole interior is accessible without reaching inside.
No. The 5379 is non-handed, so the same slide fits either side of the drawer. Order the quantity your drawer count requires without sorting for handedness.
The zinc finish is suited for dry indoor use. It is not rated for outdoor exposure, moisture-heavy environments, or washdown applications. For those conditions, a stainless steel slide is the right choice.
When the drawer is long, the load is real, and the position needs to stay put — open or closed — the Fulterer 5379 delivers the capacity, travel, and detent behavior that lighter cabinet slides cannot.
