H&H 300 Series is a versatile track that can be used for straight or curved applications in TV studios, theatres, and many other types of facilities. It can be curved at the factory or on-the-job to suit project requirements. Walk-along tracks can be curved to virtually any shape and length. However, cord operated tracks cannot be rigged with reverse curves and are recommended for lengths up to 60'. Serpentine layouts and long lengths require the use of 500 Series track for cord operation.
The ease of operation of a 300 Series track is dependant on several factors, including the radius of the curve. In general, the track operates best around gentle curves. Whenever possible, it is recommended that layouts be designed with a radius of 4 feet or larger. Tighter curves will result in a system that requires additional effort to operate.
A variety of track switching devices are available for use with 300 Series Walk-Along tracks.
