RC-1 ProPlus™ Resilient Channel (RCUR)


Made of 22mil steel to provide a stiffer resilient channel.


Made of 22mil steel to provide a stiffer resilient channel (RC-1 ProPlus) is one of the most effective, low-cost methods of improving sound transmission loss through wood and steel frame partitions. It is used as a cross-furring member for resilient attachment of gypsum. Knurled face makes wallboard application easier.

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 pre-punched for screw attachments to wood or steel framing members. Nails are not recommended for attaching RC-1 ProPlus heavy-duty resilient channel to framing members.
