Historically, floor squeaks have been a significant callback problem for home builders. To provide builders a possible solution to this problem, Paslode developed the TetraGRIP™ fastening system and had Home Innovation Research Labs test its "squeak reduction/elimination" capabilities. The testing conducted was based on a test method developed by Home Innovation Labs for determining the propensity of a subfloor fastener to cause squeaks due to relative movement between the subfloor and the fastener.
