Primacoustic Offset impalers offer an effective method to increase bass absorption by introducing an air space behind the panel. This unique impaler features a U-shaped design with pivoting darts for left-hand or right-hand installations. The deep 3½” stand-off matches that of a typical 2”x4” making it easy to use in conjunction with standard building supplies. By adding the cavity, an additional octave of bass attenuation can be achieved!
Comes in a pack of 8.
Each impaler features a series of sharp protruding darts that penetrate the panel to secure it in place. To ensure panels do not get dislodged after installation, applying a dab of construction adhesive to the impaler during the mounting process adds another level of security and reduces opportunity for tampering. Impalers are installed using typical sheet rock anchors and screws.
Alternate installations that can be considered include direct screw down using a long screw and retaining washer. This is typically done using a standard screw and a wide faced washer to hold the panel in place. This is a good option in industrial installations where panels may find themselves in harms way or need to be secured on ceilings. Velcro is also a possible option where light duty installations are needed. Finally, for permanent installations, construction adhesive is used by applying a generous bead around the circumference and then crossing from corner to corner. Use a surface impaler to anchor the panel while the adhesive cures.
