The DuoHM cavity plug covers all common building material thicknesses from 9.5-30mm with just one length. 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. Thanks to the metric internal thread, the attachment can be screwed in and unscrewed several times. In addition to the screw supplied, the DuoHM can also be used with other metric screws.

The nylon anti-rotation lock protects the surface of the building material from damage. Due to the narrow plug edge, the anchor is no longer visible behind the attachment.
