Gripstrip is a closed cell backer rod that is shaped like a trapezoid. The flat surface allows for easier application of chinking material. Additionally, it promotes 2-point sealant adhesion while it controls the depth of the sealant materials. Gripstrip can be used on the interior or exterior of your log structure. Finally, GripStrip’s unique trapezoidal design compresses to provide an excellent fit to the logs while requiring no additional adhesive or staples.
