572924 DuoHM 5x55 S TX, 25 pieces

The DuoHM cavity dowel covers all common building material thicknesses of 9.5 - 30 mm with just one length. Due to the unique combination of nylon and metal, the DuoHM delivers high loads and maximum flexibility in panel building materials. The metal sleeve folds behind the building material and presses against the back of the panel, whilst the nylon base knots in the panel. The DuoHM can be installed quickly and easily using a cordless screwdriver without the need for additional setting tools. In addition to the supplied screw, the DuoHM can also be used with other metric screws. The nylon anti-rotation guard protects the surface of the building material from damage. As the narrow dowel edge, the dowel behind the component is invisible.
