Step Ladder Folding Assist
A device for the purpose of assisting in the opening and closing of a step ladder. The inventive device is targeted for the safe engaging and disengaging of the spreader lock. The spreader lock of most step ladders requires an upward force to be applied by the operator's hand to the underside of the spreader lock. With the use of this device, the upward force can be applied indirectly and allow for the user's hands to safely remain free of the moving parts of the front rail, rear rail, and spreader.Page 1
