I do furniture & equipment assembly. A repeat customer (I assembled a swingset last year for him) hired me to assemble this.
Product is placed as per customers instructions.
There is no iron in the bolts. So our magnets were useless, and magnets help on job like this. It will help to have a quality 10mm ratchet with high tooth count. Some of the bolts are in tight spots, awkward to start and drive.
Three of us got it done in one long, hot day.
