 Rynglok Design

Eaton’s Rynglok design

makes it possible to exceed
lightning strike requirements
by conducting high surface
currents “spark free”.
The continuous metal contact
insures very low electrical
resistance which prevents
sparking in critical applications
such as aircraft fuel tanks. Lightning Strike — Spark-Free Connection

Rynglok Saves Time and Money

and logistics requirements method greatly reduces repair
