We created the PRO FMW-25 Universal Metal washers for electricians and HVAC installers who need to attach various membranes and grids to concrete and steel.
The reliable PRO FMW-25 universal metal ring helps you attach mesh, wall membranes and other delicate items to concrete and steel. The ring has a diameter of 25 mm. You can attach the rings with our GNB 18V tackers with the standard nose and magnetic ring. If you use the GNB 18V-38 tacker, you will need to buy the standard nose and magnetic ring separately.
