Intended for demanding applications, these reels include an oil- and water-resistant extension cord.

Sure-Grip Automatic-Wind Cord Reels

The plug and outlets on these reels form an extra-tight connection with any device to keep it from detaching. They’re marked with a green dot to confirm that they’re hospital grade.
