The OMG CR-Double Base Sheet Fastener Assembly is a one-piece unit precision formed from G-90 galvanized steel and coated for corrosion resistance. This fastener is designed to secure base sheets to a minimum 2-inch thickness of poured lightweight insulating concrete in applications that require maximum withdrawal resistance. An OMG Pogo Stick should be used to install the fastener.
Lightweight insulating concrete must be surface dry and resonably smooth prior to roofing. For best performance, the fastener should always be installed perpendicular to the substrate.
