One each of the four sets. Replacing the traditional layout board of plywood, wood strips and horseshoe nails, the layout block system consists of aluminum 'L' blocks that cannot warp or absorb flux, and long aluminum pushpins. The layout blocks are used with homosote board or ceiling tile for quick and easy positioning of panel layouts. Additional layout add-ons can expand the system with a variety of blocks for positioning any project, from windows to lampshades to tiny boxes!

Individual sizes available: 6" Add-Ons (#LB01), 12" Add-Ons (#LB02), 27" Add-Ons (#LB17), and 23" Add-Ons (#LB23).
