I am inclined to buy a bunch of the pocket clips used on RRT-01
everything you need to know about jetbeam clips
It looks like the EX11.2 have screw holes that match the McGizmo clip spacing that Jetbeam uses on the RRT-01…
note the long clip pictured is Ti, available from Jetbeam for $2, it was used on the TCR-1.
I have not actually tried to thread the screws into the holes, because I gave my last set of spare screws away.
I just emailed an order for some Clips to info@jetbeamlight.com, asking if they can ship to USA at this time. Last time I did this, the clips were $1 each for the Jetbeam RRT-01 versions, and shipping was $7. The clips come with screws and a wrench. One stop shop.
Warning, the screws are easy to overtighten and strip the aluminium host. After which, loctite or JB Weld have worked for me. I have not yet tried screwing a clip into the Nitecore EX11.2 host, so fit is not confirmed, but looks very promising.
Which clip length do you like, long or short?
