Clark Masts is a pioneer of the air operated telescopic mast. For many applications the pneumatic system of extension has useful advantages. Unlike hydraulic masts, Clark masts are light, they use a working fluid which is also light, does not have to be carried as part of the mast, and if leakage occurs, the mast remains clean.

Clark Masts' 40 years experience in manufacturing air operated masts allows them to offer the widest choice of models and the best engineered detail, as a glance through this online catalogue will show.
