Hand crank for SL3000, Q028 manual hand crank aka K07-50303 used to manually open the older Elite and Liftmaster SL3000 slide gate operators
Make sure to disconnect power to unit before using (even if the power is out to the property)
Q028 was the older part number used by Elite
k07-50303 is the new part number used by Liftmaster
Both part numbers refer to the same part.
