Here at Bathroom Machineries, we got quite tired of fighting with Crane and Standard lavatory drains while trying to remove them. So, we sat down and designed a tool that drops down though the top of the drain and will engage with the openings in the sides on the existing drain assemblies. Once that’s done, you can have a helper hold the tool while you turn the nut under the sink. This tool is made of solid steel, and the cross-piece that engages the drain is retained by a set screw. Comes in a PVC tube for easy storage.
