U-Bolts for Round Posts are used to secure Dog-Proofer (Straight and Houdini) Arms to round fence posts which are most commonly found on chain link fencing. The U-Bolts come in pairs of two with four washers and nuts. One set will attach one arm to a round post (so if you are attaching a 100 kit to chain link you will need 12 sets of U-Bolts).
We offer U-bolts for the three most common residential chain link post sizes; 1 5/8" typically used for in-line posts and also gate tubing, 2" typically used for corner, gate and end posts but also used as line posts for some fences and 2 1/2" used for corner, gate and end posts.
The easiest way to determine the diameter of round chain link posts is to use a cloth tape measure (like used in sewing) and wrap it around the post.
1 5/8" post has a circumference about 5 1/4" 2" post has a circumference of about 6" 2 1/2" post has a circumference of about 7 1/2"
Please check your post sizes and order appropriately.
