Hi Kent. I’ve had the same problem. I can’t find ones at Lowes, Home Depot, ACE, ect… that fit. If someone has, please post the brand and part number. I need both glands for B11s. For the fiber and network cable. As far as a C5 goes, that one is going to be proprietary. Mimosa needs a way for us to buy these parts easily. Dustin helps when he can and it’s always greatly appreciated but, I don’t think he has unlimited spare parts. If he does, please send me some also. I really need at-least 4 of each please. I really need them and I don’t know what to do.
