The Spider Holster Hand Strap is designed to work with your DSLR camera and lens with or
without a vertical grip. Because the bottom of the strap mounts between
your camera and any tripod plate, it won't interfere with the tripod
mounting – you can leave it attached to your camera. The top of the
SpiderPro strap is attached by threading it to your camera's upper strap
lug. Both the bottom and top of strap are easily adjusted to the size
of your hand.
The strap's curved S-shape and optional, snap-on wrist strap contribute
to making your camera feel almost as though it was an extension of your
arm. The S-shape is designed to allow unfettered access to the battery
door and memory card slots. While it provides added support, the use of
the snap-on wrist strap is a matter of personal preference. The
foam-padding and leather backing provide both comfort and optimal hand
positioning for manipulating all camera controls. In addition, with
repeated use, the leather will conform to the unique shape of your hand
for a custom-like fit.
