15 Yard Capacity , Slide in Chip and Leaf Box for dump truck use. This box was manufactured and sold by Concord Road Equipment. We have used this box seasonally for 20 plus years. I cannot guarantee an exact age. We believe they were bought between 2003 and 2004 but that is not for sure. We use them in 11 foot dump beds. I believe it could be easily modified to fit shorter dump beds if needed. Overall very solid, with some rust and perforation at the front lower edge and front corners. This chip box did have the dog house box to go around a telescopic hoist cylinder cut loose so it would go into a different truck that had a larger dog house. Easily welded back up to fit your truck if needed or can be used as is. The lower channel with shafts to lock into the truck gate locks, has been broken off and needs welded back in to be secured in a truck. This unit has 6 welded on tie down D rings and is also clamped in the tailgate latch for regular use. It features a 31" tall drop down tailgate. Main body is 73" tall and 76" wide. Total length of the box including the part that overhangs the end of the bed is 138.5" . The box roof has two ventilated panels made of HD expanded metal sheeting to let air out as the box is being filled. Inspections are recommended. Sold as is.
