The new Vario Line edge bolt is similar to the tried-and-tested product in terms of its key features (size, stroke, etc.). The 20 mm stroke ensures extremely secure locking and prevents the door from warping in the case of double-sided edge bolts.

The highlight of the new development is that up to four backsets can be mapped by simply moving the screwed rod connections. For edge bolts with a backset of > 40 mm, adjustment is possible for two backsets. The product launch will take place in December 2017.
