Drywall finishing material with twin-hinge construction |
摘要 |
An improved corner trim material construction such that a pair of flanges of the material, normally approximately perpendicular to one another, may “flex”, or change angle, relative to one another and the apex, or nose, of the material allowing the flanges to lay flat against the wall surface adjacent the corner onto which they are being bonded or attached. The present invention can use a single, twin or tri-hinge created by a groove running end-to-end to allow flexing. |
