Area 419 ARCALOCK 8" Universal Flat ARCA Rail Aluminum Black

The Area 419 ARCALOCK Univeral Flat Arca Rail features serrated rail sides that interface with the ARCALOCK proprietary clamp design to mechanically lock it in place so no movement is possible. The serrations are not sharp, will not damage bags or your hands. The rail is backwards compatible with standard Arca accessories, but will not be locking without the Area 419 clamp (not included).
