The 64CS 8-18 Tall Bolt Rails with Center Support by Glideaway are the perfect solution for a rail set for your queen sized bed. It can be used as a replacement frame or a new one and it works with your existing bolt up headboard and footboard to save you money. This patented hook rail bed frames are built and shaped from 4 inch wide hardened carbon steel with extra strength in the cross beam and two extra support feet. The support feet are specially made to be adjustable for beds that are taller. They adjust just by turning them from 8 to 18 inches tall for full body support. This type of system eliminates the need for wooden slats on your bed frame because the center support beam keeps the side rails in place at all times. The two rails are about 82 inches long so that you can easily reach between both the headboard and footboard to make the bed. It includes 2 side rails and one center support with two adjustable legs.
