Clark Masts YT Series of telescopic masts combine large headloads, high extended heights in relation to the retracted length. Ideal for use as mobile communications masts, telecommunications masts and at lower heights offering a competitive alternative to much larger masts. Used with a Clark Masts Roof Trolley system, the YT series can offer extended heights of 21m when fitted to a suitable van or 4x4 vehicle.
Each telescoping mast section is keyed to prevent relative rotation to the next tube allowing the complete mast to be rotated from the ground with ease if directional headloads are being deployed. YT masts can be specified with locking or non locking (plain) collars depending on the type of application and with rotating or non rotating bases.
Bearing surfaces are fitted with nylon and PTFE to guarantee smooth and effortless extension and retraction in the most demanding climatic conditions. YT masts have been tested to MIL STD 810F. When each section is fully extended an automatic collet locking system provides complete rigidity when the mast is fully extended. Double Supertork is fitted as standard giving torsional stability of +/- 1.5 degrees. For enhanced torsional stability, our bespoke Triple Supertork System gives down to 0.1 degrees of stability, dependant upon mast model/size.
Accessories can be painted to match the mast
Anti Climb Collar
An anti climb collar is available for most masts, made from steel and fitted with a rotating collar.
Domed Locking Nuts
On masts fitted with Combined Collar (Locking collar) masts, the standard handles can be replaced with domed hexagon nuts for extra security. A hexagon key tool is required for operation.

Model 185 Powerpack
Model 185 Powerpacks are suitable for larger masts from WT to TM. Powered either by vehicle electrics 12 or 24v DC or by mains power 110 or 230v AC and operated by a remote control lead 2.5m long. A built in pressure switch cuts out when the mast reaches its preset level and cuts in only when required to top up the pressure thereby saving battery power. Supplied with power connection plug.
Model 40 Powerpack
Model 40 Powerpacks are suitable for masts from ST to YT. Powered by vehicle electrics either 12 or 24v DC normally operated using a remote control lead 2.5m long. A built in pressure switch cuts out when the mast reaches its preset level and cuts in only when required to top up the pressure thereby saving battery power. Supplied with power connection plug.
Model 40E Powerpack
Model 40E Powerpacks are similar to the Model 40 and are suitable for masts from ST to YT Series but are operated by a switch directly on the facia of the unit and cannot be used with a remote control lead. Powered by vehicle electrics they have a built in pressure switch which cuts out when the preset level is reached and cut in only when required to top up air pressure thereby saving battery power.
Mounting Bracket Adjustable Lower - 13664
An adjustable lower mounting bracket for YT Series masts enabling the mast to be made vertical if the vehicle is parked on sloping ground when used in conjunction with upper mounting collar cat no. 13665.

A Nycoil cable assembly can be used in conjunction with a spreader bar fitted to the mast head to guide, protect and manage cables for video cameras, antenna or other equipment fitted to the mast. Cables which are unable to be internally fitted such as coaxial can be routed externally in a strong, flexible protective nylon nycoil tube. When retracted the nycoil assembly sits coiled on the vehicle roof extending when the mast is operated.
A basket assembly which fits around the mast to retain the Nycoil assembly when the mast is retracted, made to suit mast diameter.
