Grainger probably has some locks that are 2" to 2 1/8" if you use an offset latch.. the problem is my local Grainger does not carry any of them in stock. If you live in a big city that has a Graniger you might take the lock in and compare to what they actually have.. The desk people could not promise any that I would have to ordere, would work!
If anyone goes there and finds one please post the stock# back on here
Its a bad situation as I have been told the one on my 2860DS outside kitchen door can not be rekeyed
All the 1 1/8" are a no brainer.. I got mine here
Global Link Locks and Keys | RV Door Locks & Keys | RV Locks & Keys and ordered some led lighted keys also.. They seem to be decent quality and the service after the sale was good. They also sell replacement couch door locks and some can be keyed the same to the cam lock # you choose.
So anyway , anyone who finds a 2 1/8" non CH751 lock please post it here... As of now Grainger is the best bet
