Electrical Enclosure Hole Seals

Available62 products
If you're installing a new NEMA enclosure, be sure to get the right-sized hole seal to cover access holes for conduit and push buttons. The hole seal prevents cooled air from escaping to improve enclosure cooling, and keeps dirty outside air from entering the unit to extend the life of the components inside. Grainger supplies hole seals of all sizes to fit a range of standard-sized enclosure holes. You'll also find supplies and parts for maintenance and installation of your enclosures, from an aluminum enclosure AC filter to mounting brackets and pedestals.
