The Manfrotto 385 Air Cushioned Center Post is a two-section air cushioned center column that comes equipped with a standard 58mm disc and three grub screws, as used on Manfrotto tripods. This means that the column can be combined with any head from the Manfrotto range.
The bottom of the column has an 80mm disc which can be screwed directly to a counter top/table or, alternatively, bolted to the included second disc on the underside of the counter top.
This post telescopes from 11.2 to 24.2 inches.
Supports up to 22 lb (10kg), with your tripod head.
