A new medium-duty stainless steel rotary latch, the R4-20 Rotary Latch, offers a durable fastening option for highly corrosive environments such as access panels and doors on off-highway and marine equipment. The compact, space-saving design makes it easy to mount the latch inside doors and is available in through-hole, metric, and imperial mounting styles. The latch can have single or two-stage latching, ensuring secure latching at low closing forces. It also features high latch-to-striker mating tolerances, making it suitable for flexible panel applications with inherent misalignment concerns.
