Un Lockable


Un-Lockable is one of Harison’s most popular Gas Spring and is available in an extensive range of sizes and with a wide range of end connectors and brackets for a wide variety of applications.

Un-Lockable  is an entirely self-contained, maintenance free, hydro pneumatic ram which is charged under pressure with an inert gas (Nitrogen).  It has the characteristics of a compression spring which, coupled with a small change in force as it extends, provides a controlled rate of movement.  At the end of the extension stroke, oil damping occurs due to a hydraulically cushioned zone.  These features help protect hinges and mounts by applying constant force with a damped end of travel.

Un-Lockable Gas Spring are ideally suited for use on vehicles of any size, machine guards, lockers, access panels, hood supports, hatch covers, lids and much more.
