In order to provide an easy and quick opening system as an optional and safety element, our covers can incorporate a new indoor (inside) opening system.
This opening system is equipped with one or two levers that activate the internal opening bar until the emergency closing is opened. In this way the BLOCKS WAD SCREW are unlocked where the screws of the cover are screwed, unlocking the cover easily and immediately from the inside, though externally they are closed by screws.
This opening system can be incorporated into the 1000×1000, 800×800 y 600×1300 models
With a simple change of the BLOCKS WAD SCREW we managed to revert an Inside‐Outside Opening Cover‐Top to an only Outside Opening Top.
