Konova Riser 100mm/75mm to 3/8" Bowl interface adapter Is designed to raise professional camera systems 15” above your standard tripod height. This extra clearance allows shooters to shoot over crowds and prevents people from walking through your shot. Great for conferences, churches, music venues and sporting events. This riser is intended for tripods with bowl systems supporting weights of 30 lbs or more. Remove your bowl mounted fluid head from your tripod. Attach your riser to the base of the tripod using the included 3/8 tension bolt, washer and nut. Your fluid head attaches to the riser via included 75 or 100 mm bowl adapters with your existing bowl tension handle. Also included is a 1/4 20 mounting plate for flat based fluid head mounting. Mounting directly to your tripod is recommended but can be attached to your tripod via a sturdy quick release plate for convenience. The three 1/2” aluminum posts insure that your camera is secure and shake free.
