Rigid friction brake tether
A rigid tether for use with a friction brake. The tether has a rigid handle with a brake hole at one end designed for mounting a friction brake to rotate about the brake hole. A pulley arm with pulley is attached to rotate about the other end of the handle. The pulley arm is two parallel plates, a fixed plate and a gate plate, with an axle between them on which is mounted the pulley. The plates, pulley, and handle define a rope slot. The gate plate can pivot on the axle to provide access to the rope slot.
