Expert Reply:
Hey Frank, the cross section depth of a frame is the width of the frame's channel. So the etrailer Bolt-On Swivel Mounting Plate for 3,500-lb Trailer Jacks # e52JR can fit on frame channels that are less than 3 inches in width which is due to the length of the bolts that come with it.

THank you, that makes sense. The 3 inch limit is due only to the length of the bolt. In the case of a frame made with square tubing this makes sense. Many trailers are made with channel, in which case a one inch bolt would be long enough and there would be no 3 inch limitation. Thank you for your explanation.
