Hi,
My single handle shower tub knob broke into pieces. Its the clear
plastic knob from Gerber . I couldnt find it in the local hardware
stores. Also I couldnt find a suitable universal knob, look like I have
to replace the whole set. But I dont know again what should I look for
to find a suitable replacement. The Gerber doesnt have much choice or a
good website to navigate and find a replacement part. Appreciate if
anyone point me to the right direction or a part supply on the web
where we can find replacement parts.

TIA
