End Position Lock is a safety feature where in, at completely extended position, a mechanical stopper automatically locks the gas spring from compressing. To compress, the mechanical stopper has to be unlocked manually. This feature is usually recommended on applications where hoods have to be held in open condition in a vibrating structure. E.g., on the engine hoods of earth moving machines.
This is a unique gas spring which conducts electricity if fitted in a circuit. E.g., it can be fitted on Tailgate / boot of a vehicle where the closing of the boot door is motorised and the opening is done by the gas spring.
