Asec Size 4 Overhead Door Closer with Swing Free & Hold Open Facility

The Size 4 Overhead Door Closer from ASEC is a fire tested door closer that provides both a swing free and a hold open function, with a simple conversion method thanks to a plug-in power loop. The swing free function allows the door to remain open, without any resistance from the closer – the hold open function retains the door in an open position. When a fire alarm is activated, power to the unit is cut off and the closer will automatically allow the door to close.

With a maximum door weight of 80kg and width of 1100mm, the ASEC Size 4 Overhead Door Closer is ideal for use where the Equality Act is taken into consideration like care homes and hospitals, as well as anywhere else where low opening forces are needed.
