Manfrotto Quick Release Plate Adapter

The Manfrotto 394 is a 280 g low-profile RC4 quick-release adapter with dual bubble levels, 1/4"-20 and 3/8"-16 camera screws, and included 410PL plate—converting any RC4 head into a fast-swap, precision-aligned platform for 405/410 geared heads or studio rigs.

The Manfrotto 394 Low Profile Adapter locks into 405 or 410 geared heads and accepts the included 410PL plate for instant camera swaps. The aluminum body features two built-in spirit levels for dead-on horizontal alignment in architectural or product work. Dual captive screws ensure universal camera compatibility, while the slim 20 mm height keeps the rig compact. At 280 g, it’s the perfect upgrade for macro, repro, or studio photographers needing repeatable precision without the bulk of full QR assemblies.
