The Simpson Strong-Tie Ready-Hat furring and framing channel is excellent for framing over a CMU wall, a concrete column, or a curved transition from wall to ceiling. This versatile product is easy to form by hand to the exact shape required on the jobsite. It secures to concrete or CMU walls with powder-driven fasteners or concrete screws. Applications include furring on curved walls to create coves, barrel vaults, groin vaults, soffits, and serpentine ceilings. This channel is also great for wrapping columns or as cross-framing to eliminate drywall butt joints. The 20-guage (33 mil) steel holds its shape once formed and positioned for easy fastening.
