Shell doors

Newthex offers custom and series shell doors in either steel or aluminium that will precisely fit the contours of any hull form and are easy and safe to operate.

Customers can choose between hydraulic and electrical opening and closing. Opening options are inwards, outwards, upwards and downwards and, once open, the doors can be locked in position. Shell doors in the closed position can be locked and unlocked from the bridge or an alternative central location.
