ST Series
The ST Series of masts are the start of the Clark Masts telescopic mast range featuring keyed sections to prevent rotation. Made from high strength 3" diameter 3.25mm wall aircraft grade aluminium alloy with a choice of either non turnable or turnable versions. Plain collars or clamped (locking) collars are available.
Unlike the lighter weight non keyed QT Series, ST Series masts can be extended using a handpump, compressor or using the vehicle air system, keyed sections make them suitable for use with headloads requiring to be rotated and locked into position. The ST Series of masts also feature in the DAF mast range when a set of field legs are fitted. ST masts can be fitted permanently to vehicles or shelters, temporarily using saddle clamps or they can be used in conjunction with our range of folding tripod stands.
