These are 1-1/4 inch rectangular nylon spacers from Bainbridge Manufacturing, designed to set drawer slides away from cabinet walls, face frames, or partition panels so the slide sits at exactly the right depth and angle for clean, bind-free drawer travel.
Slide spacers solve a specific problem: the cabinet wall is in the wrong position for the slide to mount squarely. This happens most often in face-frame construction, where the interior panel sits behind the frame and leaves a gap that would tilt or recess the slide if left unaddressed. It also comes up in frameless builds with thick panel stacks, in island or peninsula cabinets where slides mount to a partition rather than a full-depth side, and in retrofit work where an old cabinet was built to a different interior dimension than the new slide requires. At 1-1/4 inches, these spacers handle the deeper offset situations that a standard thin shim cannot reach.
Nylon polyamide is the right material for this job because it machines and compresses predictably under a screw, does not split like wood shims, and does not cold-flow under sustained load the way softer plastics can. The white finish is a solid color through the material rather than a surface coat, so a trimmed or drilled spacer still shows white at the cut edge. That matters in a white-interior cabinet where a visible shim in a contrasting color reads as a mistake rather than a hardware detail.
Cabinet shops running white melamine or painted face-frame lines keep these on the bench because they eliminate the time spent hand-cutting shim stock to the right thickness and finish. Installers working retrofit projects reach for them when the existing cabinet depth puts the slide out of position for the new hardware. The 1-1/4 inch thickness is specific enough to be a deliberate order — if your offset is smaller, Bainbridge makes spacers in other thicknesses to match.
Yes. The spacer itself does not care about cabinet construction style — it just sets the slide away from whatever surface it mounts to. Face-frame installs are the most common use case at this thickness, but frameless builds with thick panels or partition walls use them the same way.
The spacer is white nylon, which reads as a clean white under most cabinet lighting. It will not be a perfect spectral match to every melamine brand, but in a mounted position behind the slide it is largely hidden and the color is close enough for production work.
The spacer screws to the cabinet wall or frame first, and the slide then mounts to the face of the spacer. This stacks the offset cleanly and keeps the slide's own mounting holes at the correct position.
Nylon polyamide cuts cleanly with a saw or utility knife. The white color runs through the material, so a trimmed edge does not expose a contrasting core.
A drawer slide that mounts off-plane binds, wears unevenly, and frustrates the end user. These white nylon spacers give you a reliable, repeatable 1-1/4 inch offset with a finish that holds up and a profile that stays put — so the slide goes in straight and stays that way.
