Awesome heavy duty, air tight drum.  I mounted a Dust Deputy to the lid.  My Rigid shop vac, the Dust Deputy and this drum work awesome to collect sawdust from my Grizzly cabinet table saw.  The Dust Deputy removes ALL of the sawdust before it gets to the shop vac keeping the filter clean.......completely clean.  The Dust Deputy, this drum and assorted hardware was less than $110........or about the cost of 7 shop vac filters.  Considering I could foul a filter in 1 weekend, this setup will pay for itself in sort order.
