This fitting really needs some self drilling metal screws and some high temp silicone shipped with it. After adjustments are made the metal screws keep the unit from moving or falling apart. The silicone seals the gaps in the folded metal. If your dryer vent outlet on the dryer itself is low to the ground and you have to connect by rotating this part, be prepared to do some metal work on the squared off corners because they will hit the floor. I ground mine off to be rounded a little.
