The classic full bodied ELS (Easy Locking System) can withstands extreme conditions while giving quick access to fittings.

With many different sizes available, this Lockwireless Anti-Rotational Fitting Solutions is designed to fit standard, MS, AS and custom nuts in order to change the nut from lockwired to lockwireless. The ELS (Easy Locking System) is an external secondary locking fracture which transforms a standard nut into a self-locking nut.
