IronRidge Integrated Grounding System and FlashFoot Products

IronRidge  released its UL2703-certified, integrated grounding system for roof-mounted PV arrays. The system includes grounding clamps, a strap for rail splicing, and a lug to connect the module row to a grounding conductor. The grounding clamp secures two adjacent modules to a rail, using its “teeth” to pierce the anodized coating on modules and rails to electrically bond them together. These clamps eliminate adding grounding hardware between modules or between modules and rails. This integrated grounding system is used for 60- or 72-cell modules, with frame depths between 31 and 51 mm. (Note: Verify additional frame parameters for compatibility.)

IronRidge also introduced its FlashFoot, which integrates a flashing, lag bolt, and L-foot, and is used for mounting rails onto a composition shingle roof. Features include a pre-installed rubber bushing to make a watertight connection between the lag bolt and the L-foot, 12- by 12-inch flashing coverage, and an elevated sealing platform for increased water shedding away from the roof penetration. This product has a 20-year warranty.
