The Guardian Fall Protection CB Anchor Series are perhaps the most proven fall protection anchors on the market. Intended for permanent applications, CB Anchors are compatible for installation onto concrete substrates. The anchor post functions to extend though roofing so that it is accessible both during and after roof construction, and is compatible for use with SRLs, vertical lifelines, horizontal lifelines, and shock absorbing lanyards. CB Anchors are composed of durable, galvanized steel, and are an excellent choice for nearly any fall protection application.
