The Sugatsune 5302 series is a full-extension side-mount ball bearing drawer slide rated at 188 lb per pair, finished in zinc for dependable indoor corrosion resistance. At a nominal 22 inch length, it suits deep utility, shop, and institutional drawers that go well beyond the standard 100 lb cabinet class.
Standard kitchen and office cabinet slides top out around 100 lb — adequate for cutlery and folders, but not for the drawers that take real abuse. A shop bench with a full set of hand tools, a garage storage unit loaded with hardware, a commercial worktop drawer carrying stacks of materials: these are the applications where a 188 lb rated slide stops being a specification detail and starts being the reason the drawer still works five years in. Full extension means the back of the drawer is always within reach, not hidden behind the cabinet face when the load is at maximum.
Zinc plating is the working standard for side-mount ball bearing slides used indoors. It protects the steel members from rust and surface oxidation through years of indoor service without adding decorative complexity. On a drawer that lives inside a cabinet, the slide finish is a functional choice, not a visual one — zinc keeps the steel sound. This is an indoor finish; it is not rated for wet, marine, or washdown environments. If corrosion resistance in a wet or exterior setting is the requirement, the 304 stainless version of the 5302 series is the right call.
Cabinet shops and contractors building shop cabinetry, utility storage, and institutional casework will find the 5302's 188 lb rating covers loads that would stress a standard slide. It also fits the commercial or light-industrial buyer who wants the smooth action of a precision ball bearing slide at a duty class above the kitchen range. At 22 inches nominal length, it suits a full-depth cabinet drawer. The non-handed design simplifies inventory: one SKU covers both sides of every drawer in the job.
Per pair. That is the working load for two slides installed on one drawer, one per side — the number the manufacturer tests and guarantees.
The 5302 series is a standard side-mount ball bearing slide; confirm the exact clearance requirement against the Sugatsune installation guide before sizing the drawer box, as the attribute is not specified in the product data for this SKU.
No. The 5302-550 is a standard-motion slide — no damper, no closing spring, no detent. The drawer stays wherever it is left.
Side-mount slides need rear support in face-frame construction. Confirm whether Sugatsune offers a compatible rear bracket for the 5302 series before specifying it in a face-frame application.
No — 22 inches is the closed slide length. Because this is a full-extension slide, the drawer travels approximately the full slide length at full open, bringing the entire drawer clear of the cabinet opening. Slide length and drawer travel are two separate facts.
When the load is real and the drawer gets used daily, the 5302 series in zinc delivers a 188 lb rated, full-extension side-mount slide that keeps moving without fuss — order one pair per drawer.
