The Leofoto GC-282C Geared Add-On Center Column is an adjustable, two-section center column extension for tripods and monopods. Made up of two lightweight yet durable 10-layer carbon fiber tubes, the GC Center Column adds height to the setup featuring the same high quality rubber grip twist leg lock and anodized aluminum hardware that come standard on Leofoto tripods. The column base has a 3/8"-16 threaded mounting socket while the top features a spring-loaded, convertible 3/8"-16 threaded mounting stud that can be slid down to reveal a 1/4"-20 threaded mounting stud, making it compatible with virtually any head.
