This Concealed Micro Rail Closer is renowned for its slimline mechanism (32mm), which has been fire tested in a 44mm fire door. The DC.3002 Cam Action Door Closer is a concealed closer with a cam and roller mechanism which makes it perfect for compliance with Approved Document M and BS 8300 recommendations. When the door is closed, it is fully concealed. The difference between this closer and the DC.3001 is that this one has a micro rail which is 20 x 30mm. This means it can be fitted into doors of a thinner width and the aperture doesn’t have to be calved out as deep as if it was for the standard rail.
