ABSTRACT:
An adjustable tripod leg is disclosed having a first leg member with an axial track and a second leg member axially movable with respect to the first. Brake shoes are associated with the second leg member and include means for following the track. Also included is a cam biasing member which selectively biases the brake shoes into frictional contact with the track to prevent relative axial motion of the leg members.
