The dual-stage telescoping Sirui SR-66C center column features a 65 mm mounting platform with a 1/4 - 3/8-inch mounting screw. Its twist column lock system deploys with a half turn.

The center column is made of 100% carbon fiber and weighs only 0,6 kg but it can handle a load of 35 kg. An elegant blue anodized locking ring provides a secure attachement to the tripod.
