  1. S***n

    Everything corresponds to the picture on which i ordered. Come with one. Complete set. Checked while one of the two, everything works. I’ll check the second one later. There was a month parcel, was tracked only in russia, by an additional track code from podolsk, which automatically appeared in the application “post of russia”. In the spring (in may) i will put in the greenhouse.

  10. S***y

    Similar door closers took in another store, the quality is good, the price is even a little less. The goods went to the vladimir region 33 days. Overall satisfied with the purchase and the store. I recommend. P.s. when mounting on the window, it should be noted that between the supports of the mechanism (forward and frame) there is a difference of 20mm, i.e. Under the frame support you need to install the spacer (i attached a piece of profile pipe 20×40).
