This is a new billet aluminum locking knob for the Delta Unisaws and their HD shaper..  This was used on the Unisaw height crank, the angle crank, the door, and the shaper door.   The OD on the knob is the same as the original but the flutes are deeper and they are easier to tighten and loosen.  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.
