Description

Leading German oil mechanism GU-BKS made of high quality materials and durability to time and use.

It is recommended in difficult cases with a force of EN 5 (heavy north doors), but without "catching" much space or being too heavy for the door to hang.

Also, the GU BKS mechanism is the only one with a 16-step fluctuation adjustment in the strength of the spring (without changes in the arm), with a special allen key contained in the package.

Alternatively you can also prefer the mechanism with STOP, which keeps the door open at the degrees you want.
