I have a B112900 shower handle that shows a set screw RP79243. The documentation I can find says it is a 3/32" allen key, but I tried that and all the other allen keys in a standard set and none of them fit. Is there some variations in set screws?

Asked by: steve
Hi steve, Thanks for your question regarding RP79243! This set screw can be removed with a 3/32" Allen wrench; however, if that does not work I recommend using a rubber band to get a more secure grip with the Allen wrench. Please feel free to contact us with any questions or for further assistance. Best Regards, Emma Digital Communications Specialist
