The two provided mounting holes for attaching short 1/4'' rod to the bottom plate. We repositioned the two mounting holes, so you don't have to remove your camera when attaching the short rod, which saves time on assembling.
The cage features multiple 1/4"-20 mounting holes for attaching accessories and mounting onto a tripod plate.
The cage can be directly attached to a Manfrotto quick release plate with two 1/4'' screws.
Note: This cage doesn't fit for SONY A7 MarkII and A7 RII. Search "SmallRig 1671" or B014QO240O for A7 MarkII and A7 RII cage.
