JAY Heavy Duty NDT Yoke
The Johnson & Allen Yoke (JAY) has been a core product in their MPI equipment range for over two decades. Manufactured in-house by Johnson & Allen the JAY has a proven track record for usability, durability and reliability. The core is encapsulated in a hard-wearing, impact and abrasion resistant polymer which makes the JAY one of the most heavy duty yokes on the NDT market. Like other Johnson & Allen yokes the JAY is fitted with a self-resetting thermal cut-out to prevent burnouts from misuse.
