About the product series Alva:
With its outstanding functions, convenient installation options and clear design, the Alva corner fitting is one of the best in its class. As the matching upper corner fitting has the same dimensions as the lower one, the fitting solution harmonises particularly well as a whole. Alva is therefore a timelessly designed all-rounder. The entire hydraulic system for the self-closing function is housed in the slim fitting. The fitting with closing force EN5 has the same dimensions of 184x70 mm as the EN3 corner fitting and therefore ensures a uniform appearance for doors of different sizes in a room. It is particularly suitable for wide and heavy doors.
