{"title":"Descenders","description":"Used as a friction brake, descenders are used to add extra friction on your rope for multiple applications. They give more uniform control and prevent excessive wear on your valuable ropes. Available in aluminum or steel. Steel wears better than aluminum but aluminum dissipates heat better and is lighter. As a rule of thumb, anytime a climber is ascending a static rope (either doubled or single) a descender should be carried to descend the rope.
