<h3>Durable, Purpose-Built Components</h3>
<p>The Dog Proofer Standard Fence Extensions are made of a single piece of 1 ⅜” diameter, 16 gauge galvanized steel tubing that is finished in a durable black powder coating. Each fence height extension has two mounting plates welded in place that work on any flat fence post, wall, or surface. Using <a href="https://www.dogproofer.com/products/u-bolt-hardware-for-round-posts"> U-bolts</a>, the extensions can also attach to round or square fence posts, making them ideal extenders of chain link fencing and decorative aluminum or wrought iron fences.</p>
<p><em>See the "Kit Contents" Tab for information on what is included in each kit size.</em></p>
<h3>Mesh Fencing Options</h3>
<p>Each dog-proof fence topper kit includes your choice of mesh fencing material. Choose either Durable Poly Mesh or Heavy-Duty Welded Wire Mesh.</p>
<p><em>Durable Poly Mesh</em> is a fencing material made with a specially formulated thermoplastic polymer formed into a grid that is not only flexible, but also very strong. This fence height extension material has a 600lb breaking strength and includes UV inhibitors that make it perfectly suited for outdoors. Poly mesh tends to be easier to install and less costly compared to the welded wire option.</p>
<p>If your dog is aggressive or tends to chew or pull at the fence with their teeth, we offer an upgraded <em>Heavy-Duty Welded Wire Mesh</em> fence extension option. This is a strong steel fence material that guards against chewing damage. The fence material is made of steel strands formed into a square grid pattern and welded together to create openings that measure 1.7” x 1.7”. The diameter of the individual wires is about 2.0-2.2mm. The welds are made with ungalvanized steel, and the whole mesh sheet is hot-dip galvanized before the black vinyl coating is applied. This makes for very strong welds and durable, long-lasting fence height extension material.</p>

<p>*Fasteners are NOT included in our fence extension kits due to the wide variety of fence types. Refer to the Installation Tab for more information on selecting the right fastener.</p>
<p>Note: arms, fences, zip ties, and other accessories are available separately. <strong>Please order according to your needs, which may require more or less than the number of components provided in the fence height extension kits.</strong><a href="https://www.dogproofer.com/pages/contact-us"> Contact us</a> if you would like assistance determining what components you will require for your specific application.</p>
<h5>Installation</h5>
<p>The dog-proof fence topper arms secure to wood posts with screws or lags, round metal posts (like for chain link) with <a href="https://www.dogproofer.com/products/u-bolt-hardware-for-round-posts"> U-Bolts</a><a href="https://dog-proofer.myshopify.com/products/u-bolt-hardware-for-2-square-post">,</a> and square metal posts with <a href="https://www.dogproofer.com/products/u-bolt-hardware-for-2-square-post">Square U-Bolts</a>.</p>
<p>Both fence material mesh options are secured to the Dog-Proofer arms with our black UV stable 120lb test <a href="https://www.dogproofer.com/products/heavy-duty-zip-ties-bag-of-100">Heavy Duty Zip Ties</a>.</p>

<h5>Helpful Information</h5>
<h3>Chain Link Fences:</h3>
<ul>
<li>You will need (2) <a href="https://www.dogproofer.com/products/u-bolt-hardware-for-round-posts">U-Bolts</a> of the appropriate size to secure the fence height extension kit’s Houdini-Proof arm around the chain link post. We sell U-Bolts in sets of two, so one set of U-Bolts is what you need to secure one arm. </li>
<li>It is not easy 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 kind of measuring tape 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, and a circumference of about 7 5/16" = 2 1/2" post. Measure all posts when installing your fence extension system because chain link fences have bigger posts at corners, endpoints, and gates.</li>
<li>The tubes for gates are usually smaller (1 3/8" diameter) tubes. To secure our fence height extension system, use a 1 5/8" U-Bolt to a gate tube. If you have a single door gate that will open in, you 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.</li>
<li>Plan on ordering one additional<a href="https://www.dogproofer.com/products/heavy-duty-zip-ties-bag-of-100"> bag of ties</a> for use at the bottom, where the fencing material from our dog-proof fence topper meets your chain link fence. The two are secured together with one tie every 12 inches around the bottom perimeter.</li>
</ul>
<h3>Decorative Aluminum/Steel and Wrought iron Fences:</h3>
<ul>
<li>Use square U-Bolts to secure the arms to the posts. We sell the most common size of 2". Check your post size before you start installing your fence height extension kit. You can also use self-drilling/tapping screws or a drill and bolts. You will likely need to use self-drilling/tapping screws or bolts at gates.</li>
<li>Plan on ordering one additional <a href="https://www.dogproofer.com/products/heavy-duty-zip-ties-bag-of-100">bag of ties</a> for use at the bottom, where the fencing material from our fence extension system meets your fence. The two are secured together with one tie every 12 inches around the bottom perimeter.</li>
</ul>
<h3>Wood Fences:</h3>
<ul>
<li>Where possible, attach the fence height extension arms to the posts with outdoor wood screws or lags. At corners, you may need our Corner Adaptor Kit as the corner arm needs to point at a 45-degree angle. </li>
<li>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.</li>
<li>Inward opening gates require an arm on the gate posts and an arm on the gate on the latch side. When installing the dog-proof fence topper, cut the fence between the arm on the latch post, and the latch side of the gate and the gate will open.</li>
</ul>
<h3>Masonry Walls:</h3>
<p>Secure the arms to the wall with masonry fasteners. Use four masonry fasteners per arm.</p>
