Query: Very good product

We used to replace similar product. This was easy to install. So far is much easier to use than previous model (12 years old).Great item if you do not have any other way into a garage like a side door. We have used many times when electricity has gone out to open garage. Older model was extremely time consuming to open and needed many fdifficult turns to unscrew, then pull. This one seems to take a left turn with key & pull to release.
