Material Type of box: the box made of aluminum to resist water and prevent rusting
Material Type of box cover: the box cover is made of artinol known by its high stiffness that is used to give the required pressure on the gasket when fastened
Material Type of box cover window: the box cover window is made of transparent plastic (acrylic) to give the ability to see the electric circuits inside
Glands: two glands are used made of aluminum to give a smooth connection between the electric circuits and tether that will prevent any water leakage
Gasket: 5mm thickness black gasket is used between the box flange and the box cover to prevent any water leakage
Silicon 999: is used with gasket to give extra safety for electric circuits
