Designed for portable line arrays, Polar Focus® Crank Tower Kits allow users the ability to aim their line array from a crank up tower or Genie tower with precision. The tilt of the line array is adjustable under full load. [break] Polar Focus Crank Tower Kit was created after finding that no solution existed for an easy to install, rugged, and safe speaker and line array mounting system for crank towers. Through the combination of a large family of CTK parts, as well as the ability to custom fabricate pieces, Polar Focus is able to provide the highest quality mounting solution for your crank tower A/V mounting needs. [break] Polar Focus CTKs allow end users to mount and un-mount their equipment quickly and with minimal tools. Through intelligent application of Polar Focus components, precision pan and tilt adjustment may also be accomplished with minimal time and effort. The end result is a liability minimizing high design factor system that can save time and money in both the short and long run. Custom configurations can be made for all pick type crank towers, including, but not limited to Applied Electronics crank up lifts and mini towers, Global Truss crank stands. [break] The pan angle of Polar Focus® Crank Tower Kits work in a similar manner to an automobile`s sun visor - the pan angle will not change unless a twisting force is applied to the friction bearing. [break] Virtually any speaker or speaker combination with a combined weight that is less than the WLL of the crank tower can be mounted with the CTK family of products. Crank tower kits work with any line array with a spine frame such as the JBL VRX series, single speakers such as the Fulcrum GX series, and projector mounts using 1.5” NPT schedule 40 pipe. [break] Many other mounting options exist. Polar Focus also has the ability to design and fabricate custom mounting solutions. If you are unsure if you will be able to mount your specific system, contact Polar Focus.
