CRL ACRS Cross Adaptors are used to join posts and horizontal railings together to form four-way intersections or 'crosses' from 145 to 180 degrees. They attach in the same manner as our Straight Tee Adaptors. Each set includes two Adaptors, and comes complete with all hardware required to complete a single intersection. Important Notes: Due to the different alloy component parts and anodized finishes, the ACRS Satin Anodized Railing System's finish can be inconsistent from batch to batch. Therefore, the ACRS System and Component Parts should only be used for industrial applications like warehouses, garages, etc... where the general public is not going to scrutinize the finish.
