The Frost King and Manco stuff failed miserably (all came out of the grooves). Haven't found an exact replacement yet, but did come across a clear vinyl 1/4" bulb seal with the correct thickness flange at a glass shop that is used on shower doors. Found this lead courtesy of Yale & Chemen Spina. You have to trim one of the flanges from 1/4" down to the required 1/8". Have it included in the seals I'm looking to have made. Attached is a crossview of the shower seal. RJ
