ATM HS-1 / HS-1S Shelter Blast Hatch (Inward Opening)

ATM HS-1and ATM HS-1S shelter hatched are designed to meet and in some parameters to exceed the Finnish norms for S1 shelters. The hatch leaf is made from 20mm thick single steel plate for ATM HS-1 and 30mm steel plate for ATM HS-1S providing additional splinter protection.

ATM HS-1 hatches have a multipoint locking system with locking bolts, providing improved protection against blast wave pressure and equipped with rubber seal for gas tightness.
