If you're looking for a replacement bag / Craftsman Part # 1763272, this one is a perfect fit. Before you toss out your old bag just make sure you retain the black plastic chute as you'll need to attach the bag to that so that the chute can be inserted properly into the rear of the chipper/shredder unit itself.The original bags were made of canvas that rot plus mice just love them. :( This one is made from a heavy polyester duck fabric with heavy-duty mesh sides plus an equally heavy-duty brass two-way zipper. No doubt it'll hold up a lot longer than the original (but be sure to empty it out and wash/dry it occasionally).Elastic opening that goes over the chute was tight but had enough give so I could get it seated properly. Like original set-up, I added a zip-tie over the bag behind the chute opening for added snugness just in case.Tip: Take a photo of your old bag attached to the chute so you know which way to position the new bag on your chute. When attaching the bag to the chute, put the chute inside the bag and pull it through the elasticized bag opening which is easier than trying to shove the entire chute into the elasticized opening.There's a guy on eBay who makes and sells these for $200 a pop. Was really happy to find this alternative on Amazon for more than half less given this part has long been discontinued and you have to have one in order to operate your chipper/shredder/vacuum unit. So far, so good! Will update this review if anything changes.
