Leg Extension/Curl attachment for the Super Bench. This new attachment allows you to do leg extensions and leg curls with the Super Bench. Very heavy duty design and construction with bearing action and works with either Standard weight plates or Olympic plates with the included Olympic sleeve adapter. 200 lbs design capacity. (You can fit up to 105 lbs of Quick-Lock dumbbell weight plates on the weight holder bar, however due to the close tolerance of the plate holes some plates may be tight or not fit.) 4" diameter x 7" heavy duty foam roller pads can be set in two positions for longer or shorter legs. Also works on all the models of the Ironmaster self spotting machine benches. Note: Due to the height of the Super Bench, users over 6'2" may have a floor clearance constraint. The Bench can be rotated up a notch to get more clearance. A 3" block of wood can be used under the support foot if necessary when heavy weights are used.
