Area 419 ARCALOCK Clamp

Product Description

Ultimate compatibility with the Area 419 ARCALOCK Clamp

The Area 419 ARCALOCK clamp works with all standard ARCA/1.5″ dovetail rails. As ARCA rails grew in popularity, Area 419 saw an opportunity to improve the system. Instead of relying on friction, this clamp introduces a mechanical locking solution. This ensures your accessories stay secure—even under heavy pressure.

Designed for Speed and Precision

The ARCALOCK clamp features a proprietary two-stage screw. First, the coarse 16 TPI thread allows fast, tool-free adjustment when no tension is applied. Then, once tension begins, the thread switches to a finer 32 TPI to deliver more torque and security. This dual-thread system improves both speed and hold strength.

Versatile and Ready to Adapt

About a quarter-turn releases the clamp from the ARCALOCK detents. A full turn removes it from the rail. Additionally, it bolts directly to Atlas Bipods (QD and NC types) using factory hardware. For two-screw Atlas models, a Picatinny/1913 adapter is available.

The Area 419 ARCALOCK Clamp – made with Bipods in mind

The clamp can also be paired with a standalone barricade stop or sandwiched with an Atlas bipod. For Harris Bipods, a barricade kit is required and sold separately. A compatible Harris adapter is available and ready to ship.

Built Strong, Engineered to Stay Put

Remove the three pins to use the Area 419 ARCALOCK clamp on standard ARCA rails. You’ll get smooth, infinite sliding adjustment. Meanwhile, the moving clamp side features dual dovetails to prevent tilt. The screw and knob design keeps the clamp together—even if fully loosened.
