The first stringer can be laid on the floor using blocks and one end of each riser is attached to each bracket so that the risers are in a vertical position in relation to the stringer. The risers are attached to each bracket using blind screws through the holes in the brackets. The second stringer is then positioned over the opposite ends of the risers and attached. A clamp may be used to pull the stringers tight against the riser ends. This one step will eliminate up to 80% of the custom fitting normally required for conventional stairs.
Stair lifts are devices that are attached to the treads of staircases to safely move someone who is elderly or disabled up or down the stairs. They consist of a track, usually made of aluminum, a chair attached to the track, and the electronic controls that make the chair move up or down the track. Stair lifts are powered by alternating current (AC), which is hooked up to the household electrical system, or with direct current (DC), which uses a battery that recharges from the household electrical system, and does not require use of home electricity to work properly.
The stair is now laid on its back and (starting from the bottom step) the treads are laid in position, fitting perfectly without gaps. As each tread is positioned it is attached to the rear riser. Once all treads are positioned, the stair is laid on its side again and the end screws through the brackets are inserted. The fasteners attaching the tread to the top of the rise may be inserted as blind screws (using pocket holes in the risers) or blocks from the underside or simply using finished nails from the top.
