The JRB DuraLatchTM multi-fit, twin locking hydraulic pin-grabber coupler is designed for a wide range of OEM attachment pickups on excavators from 8mT to 50mT. The coupler delivers exceptionally strong performance in easy to operate, lightweight, compact design. ISO 13031 compliant, DuraLatch features a twin locking system that keeps attachments securely engaged in the event of lost hydraulic pressure. 



•    Fully cast body from high tensile steel, delivering exceptionally strong performance 
•    Fewer moving parts than typical couplers, with only 4 replaceable parts for easy maintenance: front latch, rear hook, latch actuator, cylinder 
•    ISO 13031 compliant twin locking back up system, including an internal gas spring cylinder which ensures the attachment remains securely engaged in a working position in the event of hydraulic loss


•    Lightweight cast frame designed to reduce engine load delivering fuel economy without compromising on machine breakout force 
•    Significantly lighter than typical excavator couplers, in some cases up to 42% lighter*
      NOTE: Weight savings based on comparable products. Relative weight dependent on range.


•    The low profile design delivers a shorter pin to tip measurement which delivers maximum breakout force for greater productivity and efficiency
•    Optimized coupler arm design to mirror excavator geometry
