Arca Clamp Adapter Plate
The Arca Adapter Plate replaces the stock StackShot Camera Mounting plate with an adapter that will allow you to attach your Arca compatible clamp to StackShot. In addition to giving you a more secure method to mount your camera it also keeps the center of gravity of the system much lower. The adapter plate has bolt holes for 3/8-16, and 1/4-20 flat socket head bolts. It also has 10-24 threaded holes so your clamp can be mounted from the top in either orientation.
The Arca Clamp Mount includes the following:
1 - Adapter Plate
2 - 1/4-20 x 1/2 Flathead Hex Bolts
2 - 10-24 x 5/8 Flathead Hex Bolts
1 - 3/8 x 16 x 1/2 Flathead Hex Bolts
4 - Allen keys
Arca Clamp Adapter Plate
The Arca Adapter Plate is used to provide a low profile, secure method to mount an Arca Clamp to StackShot. If you have already have a quick release plate on your camera then using the Arca adapter plate and a clamp on the StackShot rail makes it extremely fast and easy to add and remove the StackShot rail from your tripod stack. The animated picture below shows how the system fits together. All of the bolts and Allen keys required to attach the adapter plate to StackShot and to attach the quick release clamp to the adapter plate are included. We also manufacture a Quick Release Clamp for use with the Arca Adapter Plate. It is also compatible with third party clamps by suppliers like Wimberley or Really Right Stuff
The adapter plate has many different mounting options to make it compatible with many of the Arca compatible clamps on the market. You can download the bolt pattern for the adapter plate here. For many Arca Clamps it is possible to mount the clamp from the top of the adapter plate, the adapter plate also allows for rotating the clamp this allows the camera to be mounted by either the lens foot or the base of the camera.
The dovetail machined into the base of StackShot is designed so you can use the Arca Clamp that is mounted on your tripod to hold StackShot without having to purchase another quick release plate.
