One panel plug for all common building material thicknesses.

Cavity fixing DuoHM

The DuoHM cavity plug covers all common building material thicknesses from 9.5 - 30 mm 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.

Advantages

The DuoHM can be installed quickly and easily using a cordless screwdriver without additional setting tools. This reduces installation time by up to 50% compared to conventional panel plugs.
The unique 2-component technology meets high load requirements. The metal sleeve presses against the back of the panel and the nylon base body knots in the building material.
One plug length covers all common building material thicknesses from 9.5-30mm for flexible and cost-efficient use.
Thanks to the metric internal thread, the screw can be unscrewed and screwed in again several times.
The nylon anti-rotation lock ensures correct installation and also prevents damage to the building material.
The fixing is no longer visible behind the attachment part due to the narrow plug edge.

Functionality

The DuoHM is suitable for panel thicknesses from 9.5 to 30 mm.
The DuoHM is mounted as a push-fit installation, i.e. the screw is installed directly through the attachment part.
The metal sleeve folds behind the building material and presses against the back of the panel, the nylon base body knots in the building material.
Installation is only complete when the tightening torque is clearly noticeable and the metal sleeve is fully pressed against the panel.
Thanks to the metric internal thread, the attachment can be fastened and unfastened several times.
