SU-III RWRT Watertight Blast Hatch with Top Opening

SU-III RWRT shelter hatches are designed for up to 440 kPa (4.4 bar) blast pressure (top opening) according to existing technical norms for civil defence shelters. The hatch leaf is made from reinforced beams with cover plates and the hatch equipped with gas lift supports for easier opening. The hatches can be upgraded with armour plates for splinter / ballistic protection and special materials for fire resistance.

SU-III RWRT hatches have a multipoint locking system with lever, providing improved protection against blast wave pressure and equipped with rubber seal for gas tightness.
