It has a built-in braking spur which can be used to create extra friction during a descent without having to use an additional connector.
It has a multi-functional control lever with an automatic return mechanism. By actioning the control lever, the operator can descend at a controlled speed, always keeping hold of the free end of the rope. The lever lets you stop the descent at the desired working position without having to tie off the device, where the lever can be moved to the stand-by position to prevent it being accidentally opened.
Sparrow is also equipped with a safety decelerating system EBS (Extraordinary braking system) that activates decreasing the descending speed when the control lever is accidentally pulled strongly downwards.
The safety gate on the moving side plate helps prevent dropping the device and facilitates installation of the rope when passing intermediate anchors.
