This normally comes in 5 parts of (what I needed only 4 parts - Attachment for steel frames I did not need). Within 30 seconds it is put together. It can be mounted on the left and right stop doors. Three different closing strengths are possible.
I wanted to use the medium thickness, but the spring bolt was not in the corresponding small hole of the bracket. Here I had to deburr the Plungers something only once. Then applied a little grease and then assembled. The small aufzusteckende plastic cap (with me mounted below), holds together the entire mechanism, whether the long going well? The same problem location as the old NO! Here I would have liked something with thread.
Why? -> The small plastic cap is in DIN left doors mounted from below (at the right doors from above), which I find a bit critical. This may over time not solve, otherwise the spring flying down out.
It is good that the temple contains already a felt element (at my previous one self-adhesive felt was doing), so the frame is protected and you have to stick it nothing.
Basically works the part and stops by the spring force of its own accord at the door, but I have a precaution even screwed a little screw in through the holes in the slip-on element.
The door is good but returned in most cases not closed. The product is high for the price still okay.
1 to 1.5 star deduction for the non-matching Plungers and the bottom just plugged in DIN left doors not so trustful plastic cap. A few pictures I have contributed in the customer area .... 3.5 stars.
Addendum after 1,5 years: the time I had bought 2 NO and both of "creak" now quite noisy when returning the door. So simple wear after a short time.
