This is a 3/4 inch rectangular nylon drawer slide spacer from Bainbridge Manufacturing, built to shift a slide's mounting position by exactly 3/4 inch where the cabinet interior needs a correction or offset before hardware goes in.
Slide spacers do a specific job: they move the slide's mounting surface outward from the cabinet panel by a fixed amount. A 3/4 inch spacer is the right call in several common situations. Face-frame cabinets with a deeper-than-standard stile overhang sometimes leave the slide sitting too far back from the drawer box side; a spacer at the rear bracket or along the cabinet panel brings the slide out to where the drawer clears evenly. Frameless cabinets with a thick melamine or plywood panel edge — or cabinets where an insert or liner has reduced the interior width — may need the same correction on one or both sides. In retrofit and repair work, a warped or bowed panel sometimes pulls one slide out of parallel with the other; a spacer at the high point restores the alignment without re-building the box. The 3/4 inch thickness covers offsets that a 1/2 inch spacer undershoots but where a full 1 inch spacer would overcompensate.
Polyamide nylon is the material of choice for slide spacers because it compresses only negligibly under fastener torque, will not split along a grain the way wood shims do, and holds its stated thickness year after year regardless of humidity changes inside the cabinet. The matte Black color is molded through the material, so scratches and cuts from screw installation do not show raw plastic. Black nylon also pairs naturally with dark-finished slides and cabinet hardware without calling attention to itself on the cabinet wall.
Cabinet shops running face-frame production lines will find this spacer useful wherever the face-frame depth varies between cabinet runs and the slide position needs a consistent correction. Installers retrofitting slides into existing casework — where panel irregularities or previous hardware have left the mounting surface uneven — can use these spacers to true up both sides before committing the slide screws. Designers specifying slide layouts in deep face-frame or panel-lined interiors can call out this 3/4 inch spacer explicitly as part of the hardware schedule so the installer has the right offset on hand. Because the mount is screw-on, there is no special tooling and no adhesive cure time — the spacer goes on, the slide goes on top, and the drawer follows.
Stacking is mechanically possible, but the fastener length must span both spacers and still reach solid material in the panel. Use a single spacer at the correct thickness whenever one is available for your target offset; confirm your screw length covers the combined depth before stacking.
Yes. The screw-on nylon spacer mounts to the panel surface in either construction type. In face-frame work it is most often used at the rear bracket position; in frameless work it goes directly on the panel side wherever an offset is needed.
The color is integral to the molded nylon — there is no surface coating to chip or peel during screw installation.
The spacer is a generic offset shim that sits between the cabinet panel and any screw-on slide or bracket; it is not engineered to a specific slide brand. Confirm the combined thickness does not exceed your available side clearance for the slide you are mounting.
One missing offset spacer can stall a drawer installation while the crew improvises a shim — having the right 3/4 inch Black nylon spacer on hand means the correction takes seconds and the drawer goes in level the first time.
