Opening and closing a large sliding garage type door at the loading dock to the building my studio is in. Recorded with a shure sm7b by running 100ft of xlr cables down the hall from studio to door.
Recorded in home studio, you can use this effect free for your works. The sound on recorded is a zipper of a cartridge case or bag, the zipper close and open.
