Grip-Rite SpeedSpike - the first widely available 4-1/2 in. collated nail engineered specifically for high R-value continuous insulation systems. Built to drive through OSB/plywood, and rigid foam in a single shot, SpeedSpike delivers full 2 in. stud embedment and stronger holding power, all while cutting install time by over 5X compared to hand-driven fasteners. Designed for the demands of today's stricter IECC and IRC codes, SpeedSpike makes it easier for pros to hit insulation targets without sacrificing speed or strength. One shot. Full embedment. No compromises.
