The Opteka CBW-1 Counterbalance Weight balances the CXS-1 and CXS-2 shoulder rigs by 4.1 lbs.
A bracket, screws and a hex key come included to attach the weight to one of the rigs. Multiple weights can optionally be stacked together using the bracket that comes with each weight. Heavy camcorders or DSLRs with long lenses would require two weights.
The weight can optionally be used with Opteka's CXSB-1 Shoulder Strap Support Belt, which transforms the CXS-1 or CXS-2 into a hands free rig.
