The Sugatsune AR3-400 is a 15-3/4 inch full-extension side-mount ball bearing drawer slide built from aluminum, designed for applications where a low profile and reduced weight matter as much as smooth travel. Rated 11 lb per pair, it suits light-duty drawers in furniture, specialty cabinetry, and display cases where a steel slide would add unnecessary bulk or visual weight.
At 11 lb per pair, the AR3-400 is not sized for kitchen utility drawers or file cabinets — those jobs call for 75 to 100 lb class steel slides. The AR3 earns its place in applications where the load is light and the visual details are not. Think shallow drawers in a custom jewelry cabinet, thin-profile display case pullouts, instrument storage, or furniture pieces where a conventional steel slide is too heavy or too visually prominent beside the finished joinery. The aluminum profile blends with anodized and metal-finished hardware rather than fighting it.
The slide is manufactured from aluminum, which keeps the overall weight low and gives the exposed face a natural metal tone that holds up to handling without peeling or flaking. The aluminum finish works naturally alongside other metal-finished hardware in a case or furniture piece. This is an indoor slide — aluminum without additional protective treatment is not intended for damp, humid, or washdown environments.
Custom furniture makers and display case builders are the primary buyers. If you are building a showcase, apothecary cabinet, specimen drawer unit, or any piece where the drawer hardware is part of the visible design language, the AR3's aluminum body fits the material palette in a way that zinc-plated steel does not. Designers specifying hardware for display fixtures or hospitality millwork will also find it a natural match. The 15-3/4 inch length targets moderate-depth drawers in case pieces and display furniture.
The sold-as unit is not explicitly stated in the source data — confirm quantity at checkout or with customer service before ordering for a multi-drawer project.
Side clearance for the AR3 series is not stated in the available product data. Measure the slide body before building the drawer box to confirm the required gap per side.
Yes — full extension means the drawer member travels the full slide length, bringing the entire drawer box out to the cabinet face so the back of the drawer is reachable.
No closing mechanism is listed for this model. The drawer stays wherever it is left — there is no spring, detent, or damper in this version of the AR3.
Side-mount slides in face-frame cabinets need rear support at the back of the cabinet. Check whether Sugatsune offers a compatible rear mounting bracket for the AR3 series before specifying it for face-frame work.
When the drawer is light, the design is precise, and the hardware needs to complement the build rather than disappear behind paint, the AR3-400 in aluminum brings smooth full-extension travel in a profile that earns its place in the finished piece.
