Hollow metal frame backbend profile options diagram

Backbend Options

The backbend is the portion of the frame profile that wraps behind the wall face. Different wall types and installation conditions require different backbend configurations — full backbend for plaster or drywall, returned backbend for masonry, or no backbend for KD frames.

  • Full backbend: standard for drywall and plaster walls
  • Returned backbend: for masonry conditions
  • No backbend: used with KD frames
  • Custom profiles available
  • Backbend depth to match wall finish depth
  • Critical for proper wall reveal and fit
