The Cinevate Simplis Rails Assembly Kit enables you to attach rails to your Simplis quick release plate. The kit consists of a pair of standard 15 mm solid carbon fiber rails (each 11.8" / 30 cm long), a pair of 15 mm universal rails blocks and a tripod adapter plate. Using the rails kit, you can mount multiple photo/video accessories such as a matte box, follow focus, grip handles, shoulder pad, counterbalance systems, etc. for use with your camera system.
