Super Anchor Commercial Roof Anchor 18" (CRA) Pass Through Top 1033P


These are designed for intermediate anchors in a horizontal lifeline system that support a 3/8” diameter cable wire rope. The Pass-Through System does not require any mechanical parts and are the most economical horizontal systems on the market. The unique top fixture design allows a connector ring to be moved from one side of the top to the other side with a quick motion of moving the “O” ring through the top all while not becoming disconnected from the cable. 3 users can be tied off on the HLL system at one time. These are per-engineered permanent flat/low-slope roof anchors that come in 2 variations – a standard base-plate version or a weld on riser version. This model of CRA require a CRA End anchor, CRZ or CRA 4-Way Top as the end anchors in the horizontal lifeline system and spacing between anchors is standard at 20’ up to 30’ with a total horizontal lifeline length up to 130’. Example:

Pass-Through top anchors are not for window washing suspension and cannot be utilized for end anchors. They can be turned into single use fall protection anchors for 1 person with the use of our PTT Adapter System by slipping it over the anchor and securing it with a detent pin. The anchors are 3rd party engineered and specified for installation with mechanical screw fasteners, bolt attachments, cast-in-place, concrete embedment anchors or field welds.

Anchors are available in 8”, 12”, 18”, 24”, 30” and 36” tall risers. Flashings for the CRA are either provided by the roofing contractor or built on site and flashed as per standard procedures for a 3” or 4.5” OD pipe. A factory supplied 35-year EPDM flashing for metal roof applications is available.
