I employ the “Paul Kloberg” method of field setup and movement. Use the thumb screws to unfasten the center section. Lift it out. Put the thumb screw back where it came from. Repeat for all four middle sections. Now go to the corners and loosen the thumbscrews by 3 turns Pop the bracket up, and fold the corner. Tighten the thumb screws to hold it in the folded position. When done you should have four side parts and four corner assembly made up of two field sections connected by the corner triangle brackets. Load the 8 parts into my car. Normally, single handed I can stand a field up / tear a field down in < 15 mins. (*)
Buy Zoro.com G2810823 you need 30, 24 for the field, 4 for the towers and 2 spares.
Initial build. Build the 4’ wall sections. On 8 of them put a single U bracket using the supplied screws, tighten hard. On the remaining 4 put 2 U brackets on the same long side, also with the supplied screws.
Take two of the 1 U sides, stand them up on the long edge, bracket up. Connect the non bracket end with the triangle corner using thumb screws. With a silver sharpy, write B or bottom. Flip over and install the top triangle plate. Repeat for the other 4 corners.
Space corners 4’ apart, drop the center sections in place. They will sit down into the U bracket, the upper brackets get thumb screws to hold them in place.
(*) One of the cool things is that I can take just the corners to a demo. Take two and flip them upside down and they now interlock with the other two corners, making an 8’ x 8’ field
