Figure 39. Spiral opening messenger - in the design of these messengers, the groove which allows the device to be placed on the cable is in the form of an S or Z. The messenger is locked on the cable by means of a rotating part at the top of the messenger. A simpler non-locking version of this messenger was produced by HYTECH, a California firm.
