Chain Tugs

Following a recent chain drop moment that destroyed my chainset, I've been trying to get hold of some chain tugs.

The bike is a 1956 Carlton Flyer, with track ends which are designed for 3/8" axles - the slots are too narrow for 10mm axles. This means that MKS Chain tugs won't fit, as the rectangular section won't fit within the axle slots (and I'm talking about the slot size, not the dropout thickness)

I've bought some of these, but they're very poor quality, and the nut keeps loosening on the rear.

Are there any other decent quality chain tugs out there that will fit?

I can't answer your question, but Nyloc nuts should sort you out.

Thanks - good idea.

Not really an answer , rather my solution as found on my new Dolan FXE.
DMR from Wiggle ,the guide would not fit into Track Ends, so I reduced these with a junior hacksaw! Result two working tugs. A faff but it works.

Bumping this thread. I have a Borough Bridge, which I think is a Genesis Day One with Alfine 8 gear hub. It had these thin chain tugs that fit between the dropout and the hub, but I dropped one in the hallway and it simply ceased to exist - couldn't find it anywhere. With just one I'm finding the wheel slips to one side. I bought some generic alloy tugs from Amazon but they're quite thick and wont fit in the dropout. Does anyone have a source for the thin ones?
