Have new plastic window glazed 3 times, there's very little space in the window rebate and I wanted to drill the new window under any circumstances. Bonding also was not an option because it might hold for a short time and eventually it falls. What I also like, the images description is here on Amazon of this article. Then I searched for what that you can put on it. The good ratings have been confirmed. Simply unpack, the holder of the pleated screws on top then attach the lower hook and the pleated click it, is really easy. Power also not give the impression that it breaks the same. Clear sees the brackets on the window and the brackets that you are drilling into the window, of course, small and unobtrusive, but if you do not want to drill, this is a good alternative and keeps very well without the window to damage. A small piece of felt is attending, you simply glued to the holder before it hangs up. The four support beams are not cheap, but you know that yes if you ordered it, rather spend a little more than get angry about parts that do not comply. Today I again 4 ordered for a second window.
