SU Type Shelter Blast Hatch with Top Opening

SU type shelter hatches with gaslift supports are designed for top opening. SU-IVR, SU-III & SU-I can be added with supporting lifting mechanism to place them horyzontally and allow top opening. The hatch leaf is made from reinforced beams with cover plates. The doors can be upgraded with armour plates for splinter / ballistic protection and specal materials for fire resistance.

SU type hatches have a multipoint locking system with gear or lever mechanisms, providing improved protection against blast wave pressure and equipped with rubber seal for gas tightness.
