Quick Mount PV QQMR-TB20P-A > T-Bolt w/ Nut, Stainless Steel, for QRail - Qnty 50

The QRail is attached to a MLPE with the same stainless steel T-Bolt and stainless steel serrated flange nut used for the roof attachment. When secured to the rail, the T-bolt crushes and pierces the aluminum oxide or paint and forms an electrical bond with the rail. The serrated flange nut pierces the coating on the MLPE bracket and forms an electrical bond that is carried through the T-Bolt to the rail.
