An angular flange for reinforcing and firestopping in the annulus between a structural panel such as a wall, ceiling or floor and a duct extending therethrough. The prefabricated angular flange includes a primary angular flange leg to be secured to the duct and a secondary angular flange leg approximately perpendicularly oriented relative thereto. Each flange includes a sealing member of flexible intumescent paper positionable therealong to facilitate firestopping therebetween. The sealing member preferably including two panels at an obtuse angle with respect to one another and being flexible to become approximately perpendicular with respect to one another responsive to securement of the angular flange to the duct and the surrounding structural panel. One or more uniquely designed corner brackets can be included for mounting the adjacently positioned angular flanges with respect to one another selectively.
