90 degree angle

All line blocks are roughly “L” shaped and have a internal 90-degree angle so that you can easily fit them to the corner of a brick.

Groove for brick line

Line blocks have a groove in them so that you can attach a brick line to it. The brick line can be knotted at its end and inserted into the groove so that it remains secure when pulled taut.

Line hooks

The hooks on a mason’s mate line block are there so that you can attach and secure the brick line. Wrapping a little of the excess brick line around the hooks will ensure that the line remains taut.
