The “90 Degree Corner” is used for gates, ending a fence run, or whatever else you may need. This is a two-piece part and uses 2 bolts and a unique locking system that includes 2 assembly clips to apply incredible pressure on the pipe. Square holes allow for the use of 2 carriage bolts that are supplied with the part. The part itself acts like a lock washer so the bolts stay tight in all hot and cold weather cycles. Available in 2 sizes, and 2 finishes. See the .PDF for more technical specifications.
