The SRTE Two Way Rescue Stop can be used with single rope from 9mm to 13mm. How to thread the rope and which way to push the lever are permanently stamped on the front cheek of the SRTE Two Way Rescue Stop. The rope should flow freely through the SRTE Two Way Rescue Stop. However, when conditions are at their worst, such as wet and/or muddy, descending may be extremely slow and difficult when you are using stiff or large diameter ropes; therefore, modify your belaying and rappelling tactics accordingly.

The lever is the primary speed control mechanism. Once you start adjusting the lever, never let go of the tail end of the rope as it is not only for balance but also is your secondary speed control mechanism.

It's easy to thread the SRTE Two Way Rescue Stop without removing the device from your harness. Although Stop Descenders only halt the descent, the SRTE Two Way Rescue Stop is easy to lock-off if you intend to be stopped for any length of time, thus making sure you are completely secure.
