Acoustic Insulation Impaling Clips are the perfect hardware for hanging sound absorbing wall panels on any wall surface. To use, attach the surface impalers to the wall, align the panel, and press the panel against the fastener with a downward motion. The “teeth” of the fastener will capture the core material and hold it firmly in place. To readjust, simply pull the panel away from the fastener, realign and press into place. Has 4 holes to be screwed on to wall.
Surface impalers measure 2 inches by 2.3 inches.
