Here we show you how our Window Mounting Clamp facilitates the installation of windows. It supports the installation on the side and from below. The clamp can be used for masonry up to 50 cm. The window can be placed on the mounting clamp and aligned with a scale that is accurate to the millimetre. With the window installation clamp, no second fitter is needed to install a window. It consists of interchangeable individual parts and has multiple possibilities of application.

We show here the simple window fastening in the roller shutter box with the RK-Fixed-DS-RA. The upward fastening stiffens the window. Sagging of window frame and roller shutter box is prevented and can even be corrected upwards. The RK-Fixed-DS-RA transfers forces such as wind load and the opening and closing of the window sash directly to the interior concrete ceiling or lintel. It is suitable for all box systems.

In this video, we present our Old Building EL-Window Mounting Angle. It has been developed for old buildings and is used for exposed reveals, in bathrooms or for interior and exterior window sills. During installation, the reveal remains undamaged, which is important for existing tiles or exposed concrete. Screwing through the window into the angle is immediately blocking. The window fixing with the Old Building EL-FMW takes place in front of the façade.
