Flannery's Metal Fast Mask® is a taper's dream come true. While many drywall trims need to be masked before mud, tape, and paint can be applied, Fast Mask® requires no such step. Fast Mask® has a built in masking strip that only needs to be pulled once the drywall and paint job is complete. By cutting one of the most tedious steps out of the installation of drywall trim, Fast Mask® reduces the contractor's costs.
