This is the cutterhead lock from a Delta 22-580 planer.  Delta no. 900141.  This  locks the arbor in place so it is easier to remove the lock bar screws. There are no returns on used parts.   Fully functional and working when removed.   Shipping on this item is free via USPS or UPS.  I do combine shipping wherever possible. I do ship internationally. Just email me and I will quote shipping to your country.
