Universal Line Holder
The Universal Line Holder come packaged in pairs and will instantly fit four-, six-, eight-, 10-, and 12-inch blocks, as well as various types of bricks. No more loose lines, no adjusting cumbersome sliding guides, and no wing nuts to tighten. A tighter line makes a truer wall, no matter what type of block or brick you’re laying. The Universal Line Holder has a compact design and is built to last, made from a single piece of extruded aluminum.
