This is a 1-1/4 inch rectangular nylon spacer from Bainbridge Manufacturing, designed to offset drawer slides from the cabinet wall where a direct flush mount is not possible or not practical. Made from black polyamide (nylon), it screws on in seconds and holds the slide at a consistent, repeatable distance from the mounting surface.
Drawer slides assume a flat, plumb cabinet side panel directly behind the slide. Real-world installs often do not cooperate: face-frame cabinets with deep stiles, retrofits into existing casework, cabinets with applied pilasters or panels, and side panels that bow or run slightly out of parallel all create a gap or misalignment between the slide and its intended mounting plane. Dropping a 1-1/4 inch spacer at the front, rear, or both mounting points moves the slide out from the wall to a usable plane without shimming with scrap or stacking hardware not designed for the job. The rectangular body distributes the clamping force across more surface area than a round washer-style spacer, which matters when the slide carries real load and the spacer is the only thing between the slide and the panel.
Nylon (polyamide) holds up where softer plastics fail under sustained compression. Unlike wood shims, it will not split, compress over time, or absorb moisture and swell. The black colorway keeps the hardware low-profile inside cabinets with dark interiors, laminate, or painted finishes — it does not stand out the way a raw zinc or white plastic spacer would. The screw-on design means no adhesive, no guesswork, and no waiting: mount it, drive the screw through the spacer into the cabinet panel, and the slide goes on over it.
Cabinet shops handling production runs in face-frame construction use spacers like this to hold consistent clearances across a batch without hand-fitting each drawer bay. Installers working on retrofit or renovation projects reach for them when the existing box was not built to the slide's assumed mounting geometry. Designers specifying handle-less or applied-panel fronts may need slides set back from the face to clear the panel thickness. Any of these situations calls for a spacer with known, reliable thickness — and one in black for jobs where the hardware will be visible from the front at full draw.
Stacking spacers is mechanically possible, but the resulting stack transfers the slide load through two interfaces instead of one, and alignment becomes harder to control. For larger offsets, a purpose-built rear mounting bracket designed for the specific slide brand and series is the more stable solution.
The spacer itself is brand-neutral — it is simply a fixed-thickness nylon block with screw holes. The slide mounts over it in the same way it would mount directly to the cabinet wall. That said, always verify the spacer thickness does not push the slide out of the required side clearance for your specific slide series.
Yes — face-frame work is one of the most common reasons to use a wall spacer of this type. The spacer bridges the gap between the inside of the face frame and the cabinet panel so the slide sits plumb and at the correct depth. In face-frame installs that also need rear support, this spacer addresses the side-wall plane; rear mounting brackets for the back of the slide are a separate requirement and sold separately.
The manufacturer's screw specification is not listed in the product data. Use a screw diameter and length appropriate for the panel material behind the spacer — the hole through the spacer body should guide the correct shank diameter. Test in scrap before running production quantities.
A slide that sits at the wrong depth or angle is a drawer that binds, rubs, or refuses to close flush. The right spacer — in the right thickness — eliminates that problem before the drawer box ever goes in.
