Step 5 · Mount the Garbage Disposal
This is often the most physically challenging step. Lift the garbage disposal up to the mounting ring. Align the three tabs on the top of the disposal with the ramped grooves on the lower mounting ring. Once aligned, turn the lower mounting ring clockwise until the disposal tabs lock securely into place. You will feel and hear it lock. Most disposals come with a small 'wrenchette' or you can use the end of a screwdriver in the lugs of the mounting ring to get the leverage needed for the final turn.
