Italy’s Dallera adopts Keep-Nut for hidden installations

Italy’s Dallera Tecnologie is now using Keep-Nut technology for hidden installation on tiles made of stone, ceramics, Corian, HPL, fibre-cement and any solid surfaces.

Keep-Nut, from Specialinsert, is a self-anchoring insert for stone and solid surfaces. It removes the need for resins or adhesives, instead assembled quickly by pressure, housed inside a cylindrical hole that is drilled with standard tools.

Keep-Nut is used on countertops, furniture, interior design and other applications. ETA certification (ETA-15/0615) is expected soon.

Dallera has 30 years experience in ventilated facades and wall cladding solutions and its Luna system is among those using the Keep-Nut technology.
