Thanks to the unique combination of nylon and metal, the DuoHM enables 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, while the plastic part knots in the panel. The DuoHM is installed quickly and easily using a cordless screwdriver without any additional setting tools. This reduces the installation time by up to 50% compared to conventional panel plugs.
