Simpson Strong-Tie Pipe Grip Ties make it easy to attach wood fence rails to metal fence posts. Galvanized fence posts typically last longer than wood posts, extending the life of the fence by helping to avoid the common problem of rotting fence posts. Now you can get the look of a wood fence with the durability of steel posts. The PGT is suitable for standard applications as well as corners and splices. Features: Install on 2-in (2-3/8-in outside diameter) vertical pipes, offsetting corners to allow for the correct rail alignment Use 3 to 4 PGTs per pipe; line up to string line Field-bend PGT flanges to fit corner and angled conditions (bend one time only) Made from 12-gauge steel Galvanized (G90) for extra corrosion resistance PGT2 attaches to rails with (4) 1/4 in. x 1-1/2 in.
