Key specs
The Topduo is the high-performance screw for any above-rafter insulation. The twin-thread geometry pulls insulation boards powerfully and settlement-free against the rafter, while the low-split tip protects the wood.
Thanks to high pull-out values it can also be used in numerous other timber structures. With special coating and TX drive.
