Review on 🌬️ Ventmate 65526 Coleman Air Conditioner Gasket Kit: 14"x14" Superior Seal and Performance by Dee Parson

Installation without problems. The standard size and thickness looked like it started with the old gasket. However, after a week, the long side of the AC unit was almost touching the roof skin. So I removed the foam pads from the short side and used all the blocks to keep the long side off the roof. Here, too, the conditioner touches the membrane. The foam is just too soft to use as a spacer to prevent AC power from reaching the roof membrane. It's also nearly $10 more expensive than other manufacturers' products listed here. I have just ordered a product from another manufacturer. Hope this works better.
