Performance Specifications:

Average 1 Person: 0.33 ft/s - 0.82 ft/s (0.1 m/s - 0.25 m/s)
Descent Speed: 2 Persons: 0.33 ft/s - 1.31 ft/s (0.1 m/s - 0.4 m/s)
The Descent Energy Rating of your product is a calculable measure of wear on the product. Descent
Energy Rating is influenced by user weight, descent height, the number of previous descents, and the
number of simultaneous users. The Maximum Descent Energy Rating is the maximum allowable Descent
Energy Rating for your product. If the product exceeds this rating, then it must be removed from service
immediately.

(Class A)
;
Each user must weigh no more than 310 lb. (140 kg).
At any time, the Descent Energy Rating of your product must not exceed its applicable value. Descent
Maximum
Energy Rating can be calculated with the following equation:
Descent
Energy Rating: E = W x H x N
Where "E" is the Descent Energy Rating in foot-pounds (ft-lb), "W" is the User Weight in pounds
(lb.), "H" is the Descent Height in feet (ft.), and "N" is the total number of descents your product has
experienced.
If, at any time, your product has a Descent Energy Rating (E) equal to or greater than its maximum,
then the product must be removed from service immediately and marked "DO NOT USE".
For metric units, the following equation should be used instead:
E = W x H x N x G
Where "E" is the Descent Energy Rating in joules (J), "W" is the User Weight in kilograms (kg), "H" is
the Descent Height in meters (m), "N" is the total number of descents your product has experienced,
and "G" is the acceleration due to gravity (9.81 m/s
Shorter length configurations will take a greater number of descents to reach the descent energy ratings
of the unit. In these instances, the rope may become the limiting factor. Guidance on the number of
descents based on rope life is listed above.
Unit service should be based on both the descent energy capacity and the rope life, whichever is
reached first based on configuration and use.
