The GAC is a preassembled MEP (mechanical, electrical and plumbing) fastener designed to attach ceiling wires to concrete. The versatile GAC assembly consists of a smooth-shank fastener attached to a 90° angle. This angle clip is for high-volume applications and works with gas-actuated concrete nailer tools as well as with common powder-actuated tools for fastening into harder substrates (structural steel or extra-hard concrete) when required.
