REV SS 5/8" ID x .95" wide made for freewheel sprockets like the Dicta Brand that are threaded all the way through. 1.37 x 24 RH tpi.
Has two 6m x 1.0 set screws and 3/16" keyway.
This Freewheel adaptor is .95" wide so it has a real stable base - used on our Staton Differentials - RIGHT SIDE.
One set screw can hold the key in place and the 2nd set screw holds the adaptor in place.
This adaptor is designed so the adaptor fits closer to the left side and the two set screws are to the right of the freewheel once it is screwed on.
It will not be as easy to remove the freewheel if needed. It still should be able to be done by using punch to un screw it.
Some brands of freewheels that are not fulley threaded will not work with this adaptor.
