A 1-3/4" channel is a bit of an oddity, Frank.

Probably a silly question, but it isn't round is it? We do have the Bulldog Collar-Lok Coupler # BD028242 that can slide over a 1-3/4" tube. This is a very uncommon style, but figured I would throw it out there, just in case.

If your channel is square or rectangular and is 1-3/4" wide, you would need to use either some washers or a 1/8" spacer on both sides. The smallest channel our couplers fit is a 2", like the # CT-3001-Z you found, but spacers/washers wouldn't hurt the capacity or anything like that. As long as everything is tightened down properly, you are good to go.

What kind of trailer are you working on?
