Description
The 3M Fire Barrier Grease Duct Access Door is the only tested and listed (OPL) door that has been fire tested in conjunction with 3M Fire Barrier Duct Wrap products.

The unique design provides for a grease and airtight seal that requires no tools for opening and closing of the access door and eliminates the need for welding. The 3M factory-built system is easy to install and reduces labor and installation time on the project.
