The CRL ACRS End Loop is made from 1-1/2" Schedule 40 Pipe and is used to complete A.D.A. Code compliant hand rails at the top or bottom of a stair or ramp. Attach both ends to 1-1/2" Schedule 40 Aluminum Pipe using either Splice Couplings or Tee Adaptors, or a combination of both, giving you total flexibility in your design.
