Check out how Top Clamps and Dori Blocks are used as part of a bricklayer's tool kit. A quick set up means you are laying bricks faster and more accurately.

BT invented both the Top Clamp and Dori Block during the 1960's and they are now found on bricky's sites all over the world.

The BT Dori Block was invented by BT Engineering and local bricklayer Dorian, and allows you to run your stringline both ways and to never fall from the profile. The BT Top Clamp secures the profile at the top and ensures the stringline doesn't pull the profile over, keeping it plumb.

BT Engineering is the world's leading manufacturer of Bricklaying Tools and Brick Saws. BT is the name bricky's trust.
