Fire brigade key
FOR UNLOCKING BARRIER POSTS
Fire brigade access roads and other regulated access roads are often secured against general traffic by removable barrier posts.
This post key, also called a fire brigade triangle (according to DIN 3223), has a zinc-plated surface. It is used to easily lock and unlock bollards and posts. Sometimes workers, construction site vehicles or even vehicles from removal companies or garden centres have to get past such barriers. With the post key with 17 mm internal triangle and 40 mm socket length, nothing stands in the way of getting through, as long as you are authorised to unlock the corresponding barrier post.
