The Triplelock - GC1 Gas Terminal - Ø 100 is an essential component for terminating a liner installed on gas-fired appliances. To ensure a secure and weatherproof installation, simply place the terminal over the protruding liner, securing it with a stainless steel screw. Finish the job with an application of acid-resistant cement around the clamp plate, extending up to the bottom holes of the cowl for optimal sealing and weatherproofing.
