Small internal profile clamp for ½ brick corners
Internal corners take different geometry from externals — the clamp has to work around the return rather than wrapping the outside edge. BT’s small internal profile clamp is purpose-shaped for exactly this job on ½ brick bricklaying work, and is typically paired with the UGCS external clamp to complete a corner setup.
The BT difference
- Securely fastened insert — won’t work loose under repeated clamping
- Domed washer — distributes load evenly, extends clamp life
- Unique corner “kink” — holds the clamp off the brick corner, preventing chips
