Extend-A-Post  1-5/8" OD Pipe Extension 2' Long - Fits a 1-5/8" Top Rail - 9 Pack

Please be aware that this product only works with a 1-5/8" top rail only. Only works with a 1-5/8" top rail and it will not work with a 1-3/8" top rail.


Price is for 9 extensions made from 1-5/8" OD (outside dimension) 2' Long. They are designed to fit onto a 1-5/8" Top Rail ONLY.  The 9 extensions included in this package provide approximately 100 feet of coverage including end posts. These extensions can be installed on existing fence, eliminating the need to remove and reinstall the top rail. Extensions are simply bolted onto existing top rail - fast and easy. Bolts are included. Extensions can also be positioned to extend fence at any angle. 

Please note: You need a secure base for your new Extensions! If you have an unstable/spinning Top Rail with an older fence perhaps, consider adding a "Top Lock Device" (TL-158-4) for the 1-5/8" and (TL-138-4) for the 1-3/8" top rail, to secure your top rail in to place before adding your new Extensions. They come in a set of 4 and 1 covers 20 feet. 

While extensions are needed for a variety of reasons, Extend-A-Post is the perfect solution for preventing pets (especially cats and dogs) from climbing and/or escaping your fence enclosure. If you have a pet who is an escape artist, the Extend-A-Post solution installed at the angle of your choosing may be the answer for you. Simply install Extend-A-Post and attach a barrier of your choice (chain link mesh, chicken wire, fabric, hardware, etc.) to create a backyard fortress for your pet. 

These fast and easy post extensions were designed and are manufactured onsite at our facility in eastern North Carolina. The design was developed and implemented by our head engineer who brings to the table more than 42 years of experience in the industry. 

TIP: Please note that 1-3/8" extensions are designed for 1-3/8" outside diameter (OD) pipe only, 1-5/8" extensions are designed for 1-5/8" OD pipe only.
