I have found this fits many brands of planers, I purchased them for my craftsman model number 351.233731 the sprockets have been discontinued by sears. Feedback from buyers are telling me that it fits more than the craftsman. If you purchase it from me and it does not fit, return it to me for a refund of the purchase price. Buy 1 to 4 I will ship it for 3.85 for those that want spares.I have found the sprockets also fits many Dewalt, ryobi, porter cable, delta and many more.
