What is CRAB?
CRAB is our line holder that makes it easy to secure the line and position it to the top edge of the brick. Used as a pair: place them on the top corners of bricks or blocks, and the taut line runs flush with the top edge of the masonry unit.
- For masonry and fence building
- Used as a pair at both ends of the line
