The chute runs about 6 feet down a 50 degree angle. It's made from 3/4" MDO (Medium Density Overlay), which resembles an 1/8" piece of masonite glued to a 5/8" piece of plywood, but unlike masonite, MDO is waterproof. At the very bottom of the chute you can see the insulation in the 1st floor celiling - the lower end opening has yet to be framed into the mudroom ceiling.
