STEEL MESH BARRIER SYSTEMS get home safely,
every day

▪ KGuard & Combisafe use different posts that are not
interchangeable. The post must be located between
No2 dimples and then twisted to lock the post into the
socket.
▪ Combisafe has a spring loaded ball catch that secures
the post. KGuard barriers are secured by the latches
on the post.
