Hi, The two rails on the side of the cage could hinder access to some of the controls on the left side of the camera but usually the side rails are shortys that run from the front spacer just 3 or six inches to hold a matte box. Same with the rear side rial mounts, Use them for a monitor holder, beer holder uhhhh I mean cold beverage holder, or other items. Watch Easom Optics for those items. message me for availability of demo units for sale. Cody
