It’s a crank
A crank, a somewhat expensive crank, however, it does what I need it to so no complaints. Service was excellent, delivered right away.
This is a replacement manual crank. Compatible with LiftMaster ELITE® Models SL3000 and SL3000ULE slide gate operators. Also known as Liftmaster K07-50303.
Since this item has been discontinued by the MFG, we will ship out an identical yet generic version.
