RCUR 23 22 0.0232 1-1/4 12
Made of 22mil steel, RC-1 ProPlus is used as a cross-
furring member for resilient attachment of gypsum. 
Knurled face makes wallboard application easier.
RC-1 ProPlus single-leg resilient channel is typically 
used for applications with multiple layers of 
gypsum board. Resilient channel should be installed 
perpendicular to the framing members with the 
attachment flange of the RC-1 ProPlus installed 
along the bottom edge. Channel is prepunched 
for screw attachments to wood or steel framing 
members. Nails are not recommended.
