QUICK FIT CLAMPS and FLANGES
For sizes 100-500mm, the Airtight "Quick Fit" ducting system uses a unique over-centre lever clamp that requires no tools or fiddly nuts and bolts.
The clamp itself makes a very strong and rigid connection while aslo helping continue a smooth internal connection and maintain the shape of the duct.
The amount of time saved by being able to quickly connect, alter and adjust each QF item is considerable with up 50% quicker installation times compared to other modular duct systems and even more compared to traditional spiral and braised installations.
