REMOVABLE MULLION

Dubuque Glass Companys Removable Mullions are very durable, low cost mullions designed for use with rim exit devices on standard and fire rated pairs of doors. The unique design of the latching head allows the mullion to be removed in seconds with one key turn, and then to be snapped back into place without needing the key.

Standard aluminum pairs of doors leak air and water
Traditional removable mullions are unsightly and do not fix air and water infiltration
