Lorient IS8010 si automatic drop seal & Finesse perimeter seal

The best option for sealing partitioning doors in an office partitioning system is an automatic drop down seal or drop down threshold. This simple idea works by closing the door into the frame a switch on the end of the threshold allows it to drop down and close up the gap. When the door is opened the switch is released and a spring draws the threshold up into the door so it doesn't bind on the carpet. It works on a similar basis to a fridge light.
