I found upon first use that this blower is only really good for left handed use. When using right handed the inlet keeps getting plugged with my pants. This is a bit over kill to make sure your clothing will not obstruct the air flow but it works. It was a snug fit and will probably stay put on it's own but I put holes for threaded inserts and some set screws to hold it on.
