The casing of HDS Systems flashlights is often the same diameter over the entire length of the flashlight. As such the universal pocket clip can be mounted with both the lens facing up and down.
The pocket clip comes with a screwdriver to attach the pocket clip. By securing the middle screw you properly secure the pocket clip. Because this screw puts pressure on the back of the clip the point of contact is a lot bigger than the screw itself, reducing the risk of scratches left behind by the clip!
Tip: carry the flashlight in your pocket, mount the pocket clip on the back. If you attach the flashlight to the edge of a cap for additional light you need to attach the pocket clip the other way around.
