EMKA MD Andy Billingham recently indicated that recessed enclosure and cabinet doors often call for a careful selection of hardware, such as internally mounted hinges, to complement the security offered by a recessed door. This is characterised by achieving very small gaps, reducing the opportunity to use any forcing tool, such as a screwdriver. Applications include dust extraction systems, HVACR and outdoor installations.
Recessed doors frequently rely on channel mounted gasket, designed to fit easily and expand into the channel for better fit and seal when the door is closed. Without a steel spine, these sections are easier to handle and install with ends that can easily be joined for a full peripheral gasket with a complete seal and improved stability. This solution also removes the spine as a site of corrosion.
Locks for recessed doors can be selected from the many modular options available but would generally be chosen from the narrow formats, which could include simple quarter turn locks or a lift handle where rod locking is required – since lift handles tend to take up less space than swing handles.
The aim is to minimise space used by the hardware components, leaving more space on the door itself, which also has to accommodate wide frame margins.
