Precision's Aluminum Alternating Tread Stair is an alternative to a traditional ships stair. These stairs allow the user to descend face-forward giving a clear view of the floor below. Precision Ladders' AT series of aluminum Alternating Tread Stairs were designed with tubular siderails to provide maximum structural integrity while keeping the overall stair weight to a minimum.
As with all Precision's products, these stairs are built to project conditions and shipped to the job site completely assembled ready for installation.
