If you use a hose reel, you can run an extension cord or air hose out through the floor of your tool trailer.
To make the hose or cord spool out smoothly, you can use a Pull-It electrical box cover as a roller fairlead for your lines.
These covers are designed for electricians to make pulling wire through a box easier while preventing damage to the wire. They are small and perfect for pulling your cord or air hose at an angle.
