The 1-3/8in Chain-Link gate elbow is a great solution when you have an unusual size gate opening that doesn't fit standard size gates. Pair the gate elbow with any 1-3/8in post or rail to build a custom size gate. The gate elbow creates the 90 degree angles for your gate. The durable aluminum construction resists rust helping to increase the longevity of the gate elbow. Includes all necessary bolts and nuts.
