We have become pretty speedy at transitioning from an open-air to an enclosed cab in a hurry. It is worth mentioning that Bestop includes a Velcro strips that attach at the top portion of the Element doors enclosures. This is for the uppers to stick to. We frankly didn’t like the way it looked and opted not to use it. This means our uppers probably don’t seal as well as they could, but it’s not something we are overly concerned with.
