Speakman Two handle tub or shower rebuild kit.
This particular kit will replace all the important bits in 1930’s and 1940’s vintage Speakman installations. Spline count is 20, stem shank is 1/2″ diameter, and stem measures 4 5/8″ long. This kit can also be used in applications where the third “center” handle operates the tub drain. This kit is very similar to the 86-SP102 kit, BE SURE to check dimensions. Thread sealant must be used on seats when installing!
