Brake Bars
Aluminum or Stainless Steel?
Rappel Bars from SMC come in two material options, Aluminum or Stainless Steel. There are several technical reasons for selecting the right material for your application.
Aluminum Bars have many advantages. It’s lighter weight and lower cost make it a great choice for uses where hauling the rack or replacing bars is a concern. But for applications with high use, aluminum will wear down faster than steel.
Stainless Steel Bars are more durable and can handle heat better from heavy loads and longer rappels. Because of this durability, stainless steel also allows for a smoother and faster rappel than would be safe with aluminum.
CAUTION! IMPORTANT NOTE! – Do not use a Tie-Off Bar to slow your descent when using the U-shape brake bars as the friction resulting when the rope passes over the straight edge of the brake bar may cause excessive wear and/or damage to the rope with the potential for system failure. Before use make sure to ask a professional or find a trainer in your area before assembly and use!
