The system should be mounted in an area low and ready, holstered in a fashion that is ready for quick access. You should un mount your system and take it to cover or unpack. To access the system, unhook the strap. Then Remove the Winder from the Holster with your non dominant hand. Using your dominant hand pull out the Spike-Strip from the holster.
Notice the Winder is in one hand and the Strip in the other hand. Regardless of the winder you use, it should be held by your non dominate hand to facilitate proper use. The Loop Winder has a beveled side and allows rope to be released when it is twisted towards traffic. When the loop is spun back, it catches the cord and allows you to pull the system in place or retrieve the system from traffic.
The other side of the Spike-Strip frame is loose and is the side that expands and opens up away from your body and onto the roadway.
You can hold and deploy the Strip with an overhand grip by holding onto both sides of the strap (smaller hands) or griping the Spike-Strip frame.
