Dock seals and shelters
Dock seals and shelters, MM series
Pro-Quai has made dock seals since 1988. The MM series covers many door and trailer sizes, and every seal is built to fit your opening.
01
What you need to know
Seals that close the gap around the trailer to keep heat, cold, water and dust out of your building.
What a dock seal does
A seal presses against the trailer around the door opening, so air, water and dust stay outside while the trailer is loaded.
Who needs it
Warehouses, food and temperature-controlled facilities, and any dock where heat loss, cold air or cleanliness matter to the operation.
Built to your opening
Send your door dimensions and trailer types. Pro-Quai recommends the right MM series model and builds it to size.
Maintenance and repair
Pro-Quai offers custom preventive maintenance programs for sealing systems, and repairs worn seals.
