Quik Trak is a system of plywood panels (7" W x 48" L x 1⁄2" H) attached to an aluminum transfer sheet. A groove down the center of the panel holds 5⁄16" Wirsbo hePEX plus tubing. To facilitate tubing turns, the Quik Trak system includes return panels with U-shaped grooves. This ensures total Quik Trak coverage and ensures the proper turning radius.
