Clip fastener for a mounting gun is designed for fastening plastic pipes to a wall, ceiling, or floor. It withstands increased mechanical loads arising during installation using a pneumatic gun. Made of high-quality materials using modern plastic molding technologies. The product is equipped with "stud-groove" type fasteners: during installation, it is possible to connect clip fasteners of different diameters. A technological hole for a dowel or screw, as well as a reduced hole for a concrete nail, is provided for element installation. The wide lugs of the product ensure reliable fixation of pipes without causing crimping. Thanks to high-quality plastic and strong reinforcing ribs, the clip fastener does not break or loosen under the influence of low and high temperatures.
