Product Expert Notes
Order one adapter for every bullnose corner where base or crown must turn a square corner, and keep a few spares on hand since boxes of 50 go far on typical homes. Mud and tape these adapters like the adjoining bead for a seamless transition. If your walls use 3/8 in. bullnose bead instead of 3/4 in., choose the matching smaller-radius adapter instead.
Cut drywall bead edges can be sharp; wear gloves and eye protection when trimming and installing metal or vinyl trim accessories.
