That is a "rear mount" and for outdoor use I'd think you'd want the
"front mount" or 83-875. That puts the washer on the inside and out of
the weather so when the connector is weatherproofed the washer is protected.
However that doesn't answer the question for a thinner washer and I
don't have an answer for that.
