This LWS Baseplate Adapter is designed to be mounted directly to our Modular 15mm LWS Baseplate Type I via 1/4″-20 threads and can also be used to adapt Manfrotto receivers. This Adapter features an ARCA receiver, enabling you to switch between a Ronin S Series Gimbal and this baseplate quickly and effortlessly. This ARCA Receiver can be easily removed, allowing you to mount other cages or camera systems directly to your Modular Baseplate via two 1/4″-20 screws. The Manfrotto Plate on the bottom allows this to connect to compatible Manfrotto Receivers, allowing it to function as a Manfrotto to ARCA Adapter.** NOTE: Some other Manfrotto/ARCA Quick Release Plates may NOT be compatible
