PUSH only & PUSH-PULL:  Supplied with “push only” or “push-pull” function. “Push only” allows manual lifting in case of power breakdown and is recommended for the opening of compartments with a unique access (engine hatches).
“Push/pull” version is required if the closing is not helped by the weight of the object moved. 

ENCODER: Struts for installation in pairs, equipped with encoded electronics and control unit to obtain a perfect synchronization, even when subject to different loads. It is possible, where permitted by law, to store up to four different and independent end positions, pre-set by the user at the time of installation, selectable with just a short press of a single button. Can also be used individually when such a precise movement is required, defining a different point of start and arrival. Come with backlit push button control and programming. Optional extension cable of 2 - 5 or 8 m.
