Fence Height Extension Kit for Dogs (Coming Soon)

Chain Link Fences:

You will need (2) U-Bolts of the appropriate size to secure each straight arm to a round chain link post. We sell U-Bolts in sets of (2), so one set of U-Bolts is what you need to secure one arm when installing your fence extender for dogs. 

It can be difficult to measure the diameter of round chain-link posts due to post caps and top rails blocking access to the top edge of posts. Use a soft tape measure like the measuring tapes used for sewing to measure the circumference of the post.

• A circumference of about 5 1/4" = 1 5/8" post;
• A circumference of about 6" = 2" post;
• A circumference of about 7 5/16" = 2 1/2" post.
• Usually, chain link fence toppers for dogs have bigger posts at corners, endpoints, and gates. 
• The gate tubes are usually a smaller (1 3/8" diameter) tube. Use a 1 5/8" U-Bolt to a gate tube.

Decorative Aluminum/Steel and Wrought Iron Fences:

• When installing your fence extender for dogs, use square U-Bolts to secure the arms to the posts.
• We sell the most common size of 2" square U-Bolts. Check your post size.
• You can also use self-drilling/tapping screws or drill and use bolts. You will likely need to use self-drilling/tapping screws or bolts at gates while installing your fence extension kit.

Chain Link & Metal Fence Gates

• If you’re installing a fence extension kit to a fence with a single door gate that will open inwards, you will need one arm on both the gate hinge and latch-to posts and an arm on the gate on the latch side.
• A double door gate opening in would require that both gates have an arm where the gates meet. For outward opening gates, you need one on each gate post and one on each side of the gate. The arms on the gate need to be set higher so that when the gate opens, the arms on the gate can pass over the arms on the posts.

Wood Fences:

• Where possible, attach the arms of your fence topper for dogs to the posts with outdoor wood screws or lags.
• At corners, you may need our Corner Adaptor Kit (must special order from USA factory) as the corner arm needs to point at a 45-degree angle. 
• Outward opening gates require an arm on both sides of the gate, and those arms need to be higher than the arms on the gate posts so the arms on the gate can swing over the arms on the posts.
• Inward opening gates require an arm on the gate posts and an arm on the gate on the latch side.
• Use fence installation tools to cut the fence between the arm on the latch post and the gate’s latch side, and the gate will open.

Masonry Walls: 

Secure the arms to the wall with masonry fasteners. You’ll need four per arm to install your fence extender for dogs. The head of the masonry screw must be large enough to catch against the 3/8" (9.5mm) opening. Use fender washers if needed.
