Straights

A raised “male” V notch runs along the top and down one side of the block while an inner “female” V notch runs along the bottom and up the other side. V-Interlock blocks are the only blocks to interlock on all four sides.

Built as two “L” shaped halves your forms lock together at the corners using two heavy-duty, over-center locking clamps. This design allows for easy set up and stripping. The clamps can be used as levers to help you pop the form open after the block has cured.
