Turn-A-Links connect easily and help you instantly create a portable roadway or working platform for as long as you need it. Turn-A-Links are ideal for usage when working in harsh sites or when the job requires several days to complete. Turn-A-Links are constructed with a galvanized coating to protect them from rusting, and to make them easier to locate on a jobsite. Made of rugged 1/2" round hot roll steel, Turn-A-Links are also available in flat hot roll steel - 1/4" thick x 3/4" wide. Other options include Single Turn-A-Links which lock mats end-to-end and/or Double Turn-A-Links which lock four (4) mats together at the corners.
