Global leader
for concealed façade fastening

If you want exciting façades, there’s no avoiding our undercutting technology. Architects can get creative without compromising on safety or design because our system not only delivers what it promises: it is also concealed.

The secret is our KEIL drilling system, which places a drill hole on the back of the façade panels without piercing them. The KEIL undercut anchor is placed in the drill hole, which guarantees an interlocking fastening free of expansion pressure. After that, the panel is simply hooked into the rear-ventilated substructure. KEIL undercut: simply ingenious!

Fastening with under­cut tech­nology

We deliver what we promise

Personal and connected

For us, family is not a question of your last name. Our employees and customers are an integral part of our third-generation family business. We know everyone personally and our barbecues are legendary. We have also been part of the industry for decades. That is how we bring together the right people for every project.

Reliable and resilient

The KEIL undercut anchor fastens without stressing the façade panels. With KEIL, there is a positive-locking fixing, free of expansion force. Due to our self-controlling system, incorrect installation is impossible. KEIL is quality made in Germany. We produce all our undercut anchors in our headquarters in Engelskirchen.

Versatile and simple

Whether we’re talking ceramics, fibre-cement or glass-fibre concrete, the KEIL undercut anchor securely fastens more than 600 different materials. Thanks to the standardised system of drilling and fastening, installation is quick and easy.

Aesthetic and precise

Fastening points on the outside of the façade? Not with us! The KEIL undercut system ensures concealed fastening. Our sophisticated drilling technology guarantees a geometric drill hole and thus absolute precision.

Sustainable and efficient

Those who build with the KEIL undercut anchor rely on a pure product made of A4 stainless steel. The large holding force of our anchor ensures particular cost-effectiveness: because high pull-out values equal a low number of anchors per panel.
