Quaker Plastics' Arrowhead Control Joint features a unique arrow-shape that presses easily into concrete. No channels obstruct installation, and the unit locks into the concrete with minimal seepage. Double-thick peel-off tape protects the top of the joint during installation. The Arrowhead Control Joint is available in 12-ft. lengths in white, tan or gray colors. A snap-on attachment creates a Full Expansion & Contraction Joint.
