“Enter through Airlock 1C, hold for decompression and air scrub.”
These nifty little kits are useful for so many things, not just representing airlocks or access points. Place them between buildings and you have a great looking covered walkway or corridor between facilities, place them up against a building to alter its profile and create little pockets and nooks for your miniatures to hide behind.
This pack of Narrow Airlocks includes multiple different lengths giving you some variation in how you set things up.
These Airlocks are 33mm wide and come in lengths of 164mm, 105mm, 66mm and 45mm long. They are 56mm tall.
