How to Install a Breakaway Square Post
- Take the sleeve (Part No. 03296) and place over the base post (Part No. 03295) until both posts are flush at the top. Use a corner bolt and square jam nut (Part No. 03290) to snuggly secure the base and sleeve together.
- Drive the base/sleeve section into the ground using a sledgehammer or driver. The base should go into the ground first. Mount the base/sleeve section into the ground until roughly 2” of the sleeve is exposed above the ground.
- Take your chosen length of square post (Part No. 03287 is 8', 03289 is 10' or 03212 is 12’) and place into exposed 2” sleeve in ground. Secure with corner bolt and square jam nut (Part No. 03290).
The SA-SO Breakaway Square Post System is the most economical way to go when choosing between posts. Our breakaway system is easy to install and affordable.
How to Splice a Breakaway Square Post
- Splices are great to use when a post is hit but undamaged portions of the post are salvageable.
- Insert the splice (Part No. 03294) halfway into one of the salvaged square post portions. Fasten the splice to the post with two drive rivets (or one corner bolt).
- Then, slip the second salvaged square post portion over the free end of the splice. Fasten the same way as above.
- The result is a repaired square post that will easily fit back into the Breakaway Square Post sleeve.
- Splices can only be used if repairing section is above bumper height.
Save money by saving a post. Splices are the way to go when portions of a post are still usable. Repair and reuse with a SA-SO splice!
