Descender - Cylinder - Miller

Use with 1/2" Rope

Descender -- Miller - 8113 Descent Device This Miller Descent Device is ideal for a variety of applications where smooth, controlled descent from an elevated position is required.

The device, controlled by the user, allows for making descent faster or slower; decelerating and stopping by applying slight outward pressure on the free end of the line; and locking in a stationary position for a hands-free work environment.
Weight 1 lb., 11 oz.

Works well with 1/2" braided rope and is made of alloy aluminum. Works well with New England Safety Blue 1/2", Solid Braided Nylon 1/2".

The Miller Descent Device operates on the principle of friction created by the work line sliding through the helical grooved contour of the aluminum mandrel.

The speed of descent depends on the number of times the work line is wrapped around the mandrel and the manual tension applied to the end of the line by the user.

The number of wraps to be used is determined by the weight of the person or the object to be lowered and the desired rate of descent.
