NO-COAT® is the world's only Structural Laminate (SLAM™) Drywall Corner System, representing a radical departure from poor-performing corner beads and a revolutionary step forward. ULTRAFLEX flex roll corner trims are ideal for off-angle applications, both short and long runs. Wide flange covers large gaps and poor framing. ULTRATRIM pre-cut corner trim lengths withstand severe impacts, settling and seismic movements without cracking, denting, chipping or peeling. ULTRA ARCH tape-on drywall arches have notched flanges that flex and conform to any arch. Stiff profile fine-tunes poor framing and creates a perfectly smooth, round drywall arch.
