ProPost Post Extension Kits - Available for 4" and 5" posts
Manufactured by New England Arbors

With the ProPost Post Extension Kit, you can install your arbor or pergola posts securely with ease. To keep costs down and the quality up, all of our products are UPS-able. Longer, extended posts aren’t. The Post Extension Kit gives the stability and dependability of an arbor or pergola installed with extended posts, used by professionals. Note: The ProPost Extension Kit is installed in concrete and provides excellent support; primarily recommended for arbor installations that will include a connecting fence or gate. It is also ideal for extreme wind areas or ground conditions that are not level from one side panel of the arbor to the other.
