McKesson Aluminum Walking Crutches are lighter than wood and provide stability and durability. Each crutch is manufactured with a double extruded center tube to ensure additional strength on weight-bearing areas. Extra thick (latex free) underarm pads and hand grips provide maximum comfort when in use. Tool free push-button adjustment allows the height of the underarm pad to be easily adjusted in 1-inch increments. Hand grips adjust separately without tools to ensure a proper fit. It can withstand a weight capacity of up to 350 lbs.
