Dock Seal This dock shelter is made of foam covered by vinyl. It suits cold storage, which requires controlled/regulated temperature. It helps protect cold air from escaping the cold storage/warehouse. Its constraint is that it requires a specific-size trailer which its platform is at the same level as factory’s floor. It requires experienced driver to park trailer at the correct position. Otherwise, it would damage the shelter.

Inflatable Dock Shelter This shelter has a blower to inflate airbag, which will seal a gap between the building wall and a trailer. It is widely used in cold storage industry and food industry. It can accommodate various trailer sizes.
