DOOR CLOSERS IN PASS-THROUGH CABINETS
When door closers are a requirement it is essential to
have thorough discussions with the cabinet users to
fully understand the requirements.
Door closer systems to cabinets can often complicate
opening when the user operates the cabinet as the door
will automatically try to close.
Therefore it should be considered to supply a door closer
system with automatic delay or hold. Furthermore, it is
possible for the system to attach to the CTS so the cabinet can be controlled from central hold and kept open
during the period of use.
