Stepped Tub Drain Crossbar Removal Key
A stepped drain key for unscrewing bathtub and shower strainers by their crossbars. It has three tiers at 39, 33 and 27 mm diameter, and each tier has a 6.5 mm cross-slot that straddles the crossbars plus a 16 mm centre pocket that clears the middle screw boss. The 64 mm scalloped grip has an 8.5 mm cross hole for a screwdriver shank, so you can use it as a tommy bar when a strainer is seized.
