Spider Pro Pin
Solid stainless steel.
Our SpiderPro Pins are cut from stainless steel and can be attached to the SpiderPro Plate, directly to the base of your camera, or to the tripod mount on your lens ring.
The SpiderPro Pin has a hole so it can be tightened using the wrench provided with the SpiderPro Plate.
Please make sure that you check periodically and tighten the Pin as hard as you can.
