Chain Link Mounting Kit TB-LINX is dedicated to Lockey USA Gate Closer. This mounting kit is compatible with: TB200/400/600 and TB250/450/650 gate closers.
The TB-LINX Kit is intended to adapt your TB200/400/600 or TB250+/450+/650+ Hydraulic Gate Closer to fence posts 3 inches or smaller. The TB-LINX kit comes with a 3 1/2 inch U-Bolt. If the post is larger than 3 inches, a larger U-Bolt must be used to match the post size.

I gather from this that if you have a post with a greater diameter youll simply need to source u-bolts accordingly. But - this makes no sense because you absolutely would need more than just bigger u-bolts therefore I called the manufacturer.
I spoke to an extremely lovely lady there by the name of Martha who told me that if you have a 4-in diameter post you have to order the following part number:
TB-LINX4-KIT
I verified with the manufacturer that you do not need to order both the TB-LINX & TB-LINX4-KIT and I also verified that the TB-LINX specifically for 3-in diameter posts and the TB-LINX4-KIT is specifically for 4-in diameter posts.
