Achieve clean, floating architectural designs with maximum stability and invisible strength. The Häfele Concealed Right-Angle Support Brackets (P-01656846) is engineered for heavy-duty hidden support, attaching securely to the side of wood wall studs before drywall installation. Designed to float stone countertops, ADA-compliant workstations, heavy vanity tops, and custom benches, this right-angle profile remains completely hidden behind your finished drywall while delivering massive weight capacities.

Manufactured from high-tensile structural steel with durable powder coating, it offers an uncompromising hidden foundation that eliminates flex, sag, and intrusive under-counter legs or diagonal knee braces.

Key Features & Benefits

• Extreme Weight Capacity: Capable of supporting heavy loads from 1,000 lbs up to 7,960 lbs (454 – 3,6180 kg) per pair, perfect for granite, quartz, marble, concrete, butcher block, and solid surface countertops.
• Concealed Side-Stud Mounting: Right-angle vertical mounting flange fastens directly to the side of wooden wall studs prior to sheetrock placement, providing a completely invisible floating aesthetic.
