TRI-ARCA Rail Attachment Plate M-LOK and R-Lock



Based on the popular Arca-Swiss quick-release system, the TRI-ARCA Rail Attachment Plate is comprised of the following features:

  • Used in conjunction with a QD Clamp style dual tension tripod head.
  • Made in the United States using U.S. 7075 T6 Aluminum.
  • Coated in black, Type III hard coat anodizing.
  • M-LOK slots on the underside of the rail attachment allow you to attach any M-LOK accessories to the TRI-ARCA Rail.
  • All M-LOK mounting hardware is included.

The Rapid Lock (R-Lock) System adds unique safety-stop features which are built in both a mounting rail and quick-release clamp that adhere to the RRS 1.5” Standard. The advantage of the system is the user has multiple “hard-stop” positions along the rail while retaining smooth edges and corners for maximum ergonomics and a snag-free interface that is inherently resistant to wearing down.
