TRI-ARCA Rail Attachment Plate




TRI-ARCA Rail Attachment Plate is based on the popular Arca-Swiss quick release system

  • Used in conjunction with a QD Clamp style dual tension tripod head.
  • Made in the USA using US 7075 T6 Aluminum.
  • Type 3 hard coat, black anodizing.
  • M-LOK Slots on the underside of the TRI-ARCA Rail also allow you to attach any M-LOK accessories to the TRI-ARCA Rail.
  • Rail comes with all M-LOK mounting hardware.


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.
