Safety spotter arms

Safety spotter arms, fits all the 80 mm x 80 mm uprights. Do you need spotter for heavy squats or presses, but there is no one around at the gym to spot you? Or they are just not strong enough, to spot your massive weights. Or if you have come to the gym to lift and not find friends. This is perfect solution for you. Safety spotter arms are made for lonely wolfs and can be attached on the squat rack/ rig without the need of nuts, bolts or tools.
