This is the left-hand, screw-on plastic rear mounting bracket for the Hettich Quadro drawer slide series, designed to support the back end of the cabinet member in face-frame cabinet installations where the cabinet side is set back from the front frame.
Face-frame cabinets set the cabinet side panel back from the front opening, which leaves the rear end of a drawer slide without direct support from the panel face. Without a rear mounting bracket, the slide back floats — causing racking, uneven travel, and premature wear on the runners. This bracket closes that gap by anchoring the back of the Quadro cabinet member to the cabinet interior at the correct position and height. It is the hardware that makes a Quadro slide work properly in traditional American face-frame construction, and it is required in that context, not optional.
The bracket is molded in plastic sized and profiled for the Quadro runner geometry. Plastic at this position keeps weight low while providing the dimensional accuracy the 2D adjustment range depends on. The screw-on design means the bracket seats against the cabinet substrate firmly, with no reliance on press-fit bores — useful in field conditions or shop installations where CNC boring at the rear position is not practical.
Cabinet shops and installers specifying Quadro slides for face-frame work need one left-hand and one right-hand rear bracket per drawer to complete the rear mounting. This listing covers the left-hand member only. Because Quadro rear brackets are series-specific, confirm that the runner version in your project matches the Quadro V6 series before ordering. Brackets from other Hettich series and from other drawer system brands will not fit the Quadro mounting geometry.
Rear brackets are required in face-frame cabinet installations, where the cabinet side is recessed behind the front frame and cannot directly support the back of the slide. In frameless cabinets with a full-depth side panel, the slide typically screws directly to the panel and rear brackets are not needed — but confirm the requirement against the Hettich Quadro installation specification for your exact runner version.
The two adjustment dimensions let you fine-tune the rear bracket position in height and one lateral direction after the bracket is screwed in place, so the slide sits parallel to the drawer bottom and level across both sides. This is the adjustment that corrects for minor variations in cabinet framing without having to re-drill.
Yes, it is handed. Left-hand means it mounts on the left side of the drawer opening as you face the cabinet front. You need one left-hand and one right-hand bracket per drawer; ordering two of this listing gives you two left-hand brackets, which will not make a working pair.
Rear brackets for the Quadro series are Quadro-specific and version-specific. Do not assume fit across Hettich series or between Quadro versions without confirming against the Hettich Quadro documentation for your runner. Accessory compatibility within the Quadro family can vary by version.
A missing rear bracket is one of the most common reasons a face-frame drawer slide installation comes up short — having the correct left-hand piece on hand before install day prevents a trip back to the supplier mid-job.
