This is made iwth a pin that runs from the working position to a foot controlled setup and uses a load that has 7.5 kg increments. A fit-in adjustment setup can use 2.5 kg increments. This may work with an air assistance setup if needed but you don't need a compressor if you are going to use the weight stack. The stack itself is fully guarded and uses a grey or white frame. This uses stack guards and custom fabrics.
