Nuheat Extra Cable Guides are used along walls, curves or where obstructions are present to ensure the cables are secure and do not float to the surface during floor prep. Each guide is 12″ long and designed to snap together for easy installation. Nuheat Extra Cable Guides can be cut into smaller pieces to accommodate your installation needs. Guides can be secured to the floor with nails, hot glue, staples or #6 1/2″ screws. 12 guides are included in each package.
