The Quadro V6 IW21 Rear Mounting Bracket is the rear anchor point for Hettich Quadro V6 undermount drawer slides in face-frame cabinet installations. Without solid rear support, the back end of the slide has nothing to register against — this bracket provides that fixed point and adds 2D side adjustment so the drawer can be trued after installation.
Face-frame cabinets set the cabinet side panel back from the door opening, which means a slide that screws flush to the side panel at the front loses its rear support point. The drawer box can shift, rack, or sit unevenly at the back when the rear end of the slide is floating. The Quadro V6 IW21 Rear Mounting Bracket attaches to the cabinet's back panel or rear rail, captures the slide's rear end, and holds it at the correct height and lateral position. The 2D adjustment — side-to-side at plus or minus 1.5 mm — gives you a fine-tuning window so the drawer front aligns after the box is hung, without pulling the slide off the wall.
The bracket is metal with a screw-on mount, consistent with the hardware quality across the Quadro V6 line. Screw-on mounting means no special boring template is required at the rear — locate the bracket, drive the screws, and the slide's back end is anchored. The metal construction holds its position under the repeated load cycles a drawer system sees in daily cabinet use.
Cabinet shops and installers fitting Hettich Quadro V6 undermount slides into face-frame cabinetry are the primary audience. If your cabinet boxes are frameless and the slides run directly on the interior side panels from front to back, a rear bracket is typically not required — but in face-frame work, rear support is not optional. Designers and contractors specifying Quadro V6 for renovation projects in traditional American kitchens with face-frame construction should include this bracket in the hardware schedule. It is also the right part when replacing a missing or damaged rear bracket on an existing Quadro V6 installation.
No. Rear mounting brackets in the Hettich line are specific to the runner series and version they are designed for. This bracket fits the Quadro V6 program. Do not assume it fits earlier Quadro versions or other Hettich runner families without confirming compatibility against the Hettich Quadro V6 installation documentation.
In a frameless cabinet, the slide typically mounts flush to the interior side panel for its full depth, so no separate rear bracket is needed. This part is intended for face-frame cabinets, where the side panel is recessed and the rear of the slide needs an independent anchor point.
IW21 refers to the inner-width specification within the Quadro V6 product family. Cross-reference the IW designation on your drawer slide order or in the Hettich Quadro V6 catalog to confirm you are ordering the correct rear bracket version. Ordering a mismatched IW bracket will result in a rear mount that does not seat the slide correctly.
The SAP description lists this as a bracket set. Confirm screw inclusion at checkout or with your sales contact, as hardware contents for accessory sets can vary by packaging run.
A Quadro V6 undermount slide performs as designed only when both ends are properly supported — and in face-frame work, that rear support comes from this bracket. Add it to your hardware schedule alongside the slides and locking devices, and the installation goes in correctly the first time.
