Here are the brackets that I have seen used on the Satoshi1 kiosk. Photos courtesy of https://tpitexas.com/
200 Series Lock Bracket - $104.99
This is commonly referred to as a “Hasp”. The supplied bolts are actually too long and they prevent the accessories tray from sliding out. The brackets comes with instructions to saw off the excess length after install. You can also just buy shorter bolts.
Indoor Security Strap - $425.00
This is commonly referred to as a “Belt”. It’s easier to install and you don’t have to worry about it bending over time as there are no bolts.
