This 25mm nylon spacer block is the accessory that makes Hettich Quadro drawer slides work in face-frame cabinet construction, positioning the slide correctly relative to the face-frame opening so installation goes in straight the first time.
In a frameless cabinet, a Quadro slide mounts flush to the interior side panel with no offset required. A face-frame cabinet is different: the front rail sits proud of the cabinet side, which shifts the effective mounting surface forward. Without a spacer, the slide sits too far back and the drawer front does not align with the opening. The 25mm spacer block closes that gap, giving the slide a flat, correctly positioned surface to attach to so the drawer hangs level and the front sits flush.
The block is molded from nylon polyamide, the same material class used throughout Hettich's system hardware for structural accessories. Polyamide holds screw threads cleanly, does not compress or deform under normal installation torque, and tolerates the humidity cycles typical of kitchen and bath cabinetry. The white finish is molded through, not a coating that chips or peels.
This spacer is the right choice for any Quadro slide installation in a face-frame cabinet where a 25mm offset is required. It is part of the Hettich Quadro system and is designed to pair with Quadro runner components — it is not compatible with other undermount or side-mount brands, and it should not be used as a general shim. Cabinet shops transitioning between frameless and face-frame work on the same Quadro platform will find this block keeps the process consistent without custom shimming on each cabinet.
The face frame adds a rail across the front of the cabinet opening that sits proud of the interior side panel. That offset pushes the drawer out of alignment if the slide is mounted directly to the panel without compensation. The 25mm block provides the exact standoff the Quadro system requires to seat the slide at the right depth.
This block is designed for the Hettich Quadro face-frame application. Quadro comes in multiple versions and configurations — confirm against your specific Quadro runner series before ordering, as some versions use version-specific brackets and accessories.
A standard drawer installation uses one slide per side, so two spacer blocks are required per drawer — one for the left and one for the right. Order in multiples of two to match your drawer count.
No. This spacer is engineered for the Quadro face-frame application at a fixed 25mm offset. Using it to shim a frameless install introduces an unintended offset and moves the slide out of its correct position.
One missing accessory can stall a whole run of face-frame drawers. Stocking the Quadro 25mm spacer block alongside your Quadro slide inventory means face-frame jobs install cleanly without hunting for a workaround.
