Installation takes only minutes. Set the low-blow and your blower on a flat surface. Line up the low-blow and blower and drill through the holes in the low-blow with a 1/4" drill bit. Remove the low-blow. Now drill the holes out to 1/2". Install the welnuts provided ( a drop of super glue is a good idea )  Attach with the thumbscrews provided and you're finished! 

If you purchase the combo, the welnuts will already be installed

built for years of service!
