Old freezer model and the door is too easy to open. I needed a more positive and tighter closure. The door seal was a bit stiff but still flexible. These bars worked great. They were easy to install in minutes. I used rivets because I prefer light metal rivets like freeze skins to screws. They are extremely easy to adjust and offer a secure closure. They arrived very quickly and all 8 bars were in perfect condition. I recommend these clasps to anyone who needs a quick, easy and secure clasp.
