The UCS linear actuators AV and Ulysses series are electromechanical products, specifically designed for use in pleasure boating, which allow the opening and closing, even partial, of heavy engine compartment doors, lockers, hatches etc. It is possible to lock the doors in all positions between total closure and complete opening, the position is then maintained by internal mechanisms that prevent accidental closing.

An emergency device also allows the possible manual opening of the compartment in the event of a power failure.
