Coupler Pin - 1/4 Diameter x 3 Long Part Number: 37201281....am curious what the distance is between the center of the pin to the inside edge of the bail. Mine measures approx. 1 7/8. Need them for securing the camper awning support arms to side of trailer when not in use. Thank you.

Hey Brent, what you are looking for is the usable width of the Coupler Pin part # 37201281 that you referenced which is 3 inches. This is the distance between the shoulder of the head of the clamp out to where the metal clip slips over the shank. This would certainly be more than the 1-7/8 inches that you need!
