One adjustable clamp that replaces four in the van
On a typical day a bricklayer might need a clamp at 300mm, 400mm, 500mm, and 560mm. Instead of carrying four fixed-length clamps, the large sliding profile clamp gives you the whole range in a single tool. Slide, lock, clamp — and move on.
Why sliding?
Fixed-length clamps are fine when the job is predictable. Real bricklaying rarely is. The sliding clamp handles irregular courses, window returns, odd corner geometries, and retrofit jobs where nothing is quite square. It’s the most-used clamp in many brickies’ kits once they’ve tried one.

My favoured clamp as works no matter when needed.
