Adjustable top clamp kit for double brick cavity work
Double-brick construction needs a top clamp that anchors to brickwork rather than timber. The UTOPIA kit is BT Engineering’s complete solution — brick-gripping brackets, adjustable cavity spanner, profile-bracket, and straight tube, all working as a single system.
What’s in the kit
- 1 × Top Clamp Straight Tube (TOP 25 Straight)
- 1 × Top Clamp T-Slider (UTOP 25 T) — adjusts to any cavity width
- 1 × Top Clamp Profile-Bracket Adjustable (TOP 25 G NEW)
- 2 × Top Clamp Brick Brackets (TOP25GI)
How it works
- Clamp the two brick brackets onto the brick veneer
- Slot the straight tube through the T-slider, engaging both brick brackets
- Fix the profile-bracket onto the bricklaying profile
- Tension — the profile is locked true and plumb, anchored off the brick veneer
