I like the rubber grommet/bushings that are included with the PFA junction boxes, but have no idea where I can buy them separately. Does anyone have a lead or source for them? I have some mounts I am considering building/printing that would benefit from using these to seal the hole.
If all else fails and you can't locate the cable glands or bushings you want, consider a blind (no hole) rubber grommet; drill the desire sized hole for the cable with a uni-bit (stepping drill bit) and if desired to pass a pre-terminated cable through the smaller hole, slit the hole from the center outward with a sharp X-acto knife or razor blade.
