Bit more to it than that - you need a set of calipers too...
Divematics are trying to make me an adapter to fit an ATX50 to my BOV. Unfortunately the sizing seems different over here - I'm hoping someone could let me know what the correct size now is please. The bit in question is the stub that you tie-wrap the rubber mouthpiece to. The oval stub will be fitted into the larger oval of the adapter and held there with a grub screw.
For reference, here are the dimensions of my (UK) Apeks ATX50; (external) max width = 21.05mm max length = 37.87mm. It's at least three years old now, maybe four. Obviously, +- 1mm is fine! A ruler is probably good enough to measure the outside width and length.
If this is the same as everyone elses then they can make me an adapter with a slot big enough to accept the reg.
I know it's a long shot, but could anyone help please?
TIA!
