Achieve clean, floating architecture without sacrificing strength or stability. The Häfele Concealed Flat Support Bracket is an industrial-grade steel bracket engineered to mount directly to wall studs before drywall installation. Designed for floating countertops, ADA-compliant workstations, floating desks, and heavy-duty shelving, this flat profile bracket remains hidden behind your finished walls while providing extreme weight-bearing support.

Crafted from heavy-gauge structural steel with smooth, durable powder coating, it offers an invisible support foundation capable of carrying thousands of pounds without unsightly leg posts or intrusive under-counter bracing.
