The EM Lock is one of the necessary accessory
in the Access Controller System too. It
is more popular then Bolt Lock.
Because the EM Lock can close the door easy
and it no need to fix the correct location
bolt hole.
In the Access Controller System, you should
select the correct type of Lock, so that
you can save the cost and you can make the
system working better.
When you have the double doors in one gate,
the double EM Lock maybe more suitable.
