S.R. Smith has made superior deck equipment for swimming pools. They create strong, high quality rails and ladders that have proven to meet the needs of any commercial pool facility. The Heavy Duty Commercial Ring Handrail front and rear legs return to mount into a single special anchor socket on either side. Depending upon the anchor chose, mounting can be either fixed for mounting at a 20 inch (on center) spacing or independent of mounting at varying distances to meet site requirements and local code. This pair of rails are polished, 1-5/8 inch O.D., 304 stainless steel with a wall thickness of .065 inch.
