The Acratech Arca-Swiss to Video Head Adapter is for DSLR and mirrorless shooters who want to mount their Arca-Swiss-based equipment on a video-style fluid head with a non-Arca-Swiss mounting system. Simply attach your video head s plate to the bottom of the adapter and mount the plate on the fluid head. This allows your fluid head to accept an Arca-Swiss or Arca-Swiss compatible plate. The adapter supports up to 25 lb, and it uses a lever lock for quickly securing your camera setup. It features a spring-loaded safety catch to help prevent your camera from accidentally sliding out of the adapter.
The top of the adapter features index marks that allow you to quickly rebalance your setup as you change lenses and accessories. The built-in bubble level helps you confirm that your camera platform is level. A central locking screw that accepts an Allen wrench or flat head screwdriver allows you to rotate the top of the adapter in 90° increments, which is useful when using long lenses, attaching the lens to the tripod, and hanging the camera off the back of the lens.
- Compatible with Acratech, Kirk, Arca-Swiss, and many other QR plates
- Large 15mm bubble level

- Long detent pin prevents plates from accidentally sliding out

- Long-lasting stainless steel hardware

The bottom of the adapter features a 3/8 -16 threaded hole with a space for a locating pin, as well as three 1/4 -20 threaded holes. This allows you to easily attach your plate to the bottom of the adapter, whether it uses a 1/4 -20 or 3/8 -16 mounting screw. You can also use the included 1/4 -20 to 3/8 -16 adapter bushing to convert a 1/4 -20 screw to 3/8 -16.
The adapter features precision-machined lugs and receivers that allow the top of the adapter to rotate independently of the base. You can quickly change the orientation of the adapter top by loosening the central screw (with an Allen wrench or flat head screwdriver), setting the position of the top and tightening the screw. The precision machining ensures the positions are precise, repeatable, and without play once the central screw is tightened.
