This is a pair of wrenches for the Delta Unisaws and the US made contractors saws.  The flat wrench for the arbor is 29/32"  and the angled wrench for the nut is 7/8".  These are US made, powder coated, and much stronger than the originals from Delta.  This includes a hanger to keep the wrenches on your saw but out of the way.  Just replace the left, front table anchor bolt and replace with this new one with the hanger.  A nice storage fix.  The hanger is available separately also.  Shipping on this item is free via USPS or UPS.
