With patented I-beam construction and a center post that limits foot piece rotation, Aluminum Adult Tall Crutches make it easier to adjust the height of the crutch to ensure the proper fit for each user. This special construction has greater strength than many traditional round-tube crutches and employs a double-extruded center that offers superior load-bearing capacity to resist breaking, especially in this most vulnerable part of the crutch. Designed for the taller patient, Aluminum Adult Tall Crutches can be adjusted from 5'10" to 6'6" and will support up to 300 lbs.
