About this model

Mounts on a weight rack with the magnets on the back of it. I used (3) 30mm x 10mm magnets. If you use 3m adhesive foam, the magnets will stick to the skull, and I used electrical tape to give the magnets some grip on the weight rack as a well as to make sure the magnets didn't come out. Using the magnets I got on Amazon, it holds 5 lbs in the chalk cutout with no problems.
