      Comments about NRS Frame U-bolt:

      After geeting a used frame and having to make adjustments I snapped off a few u-bolts. So I figured it would be a good idea to have a few spares.

            Comments about NRS Frame U-bolt:

            I ordered the oversize - 2 5/8" ones to add some side decking to an Alley Cat frame. I was using 3/4" marine ply. I would have liked the U-bolts to be 1/8"~3/16" longer as I had to recess the washers and nuts a little taking away some strength of the ply. (frame tube-1 5/8" + 3/4" ply + washer/nut-3/8"+ = 2 3/4")
            Maybe NRS could offer this length too?

                    Q:

                    Will they also fit around the 1.875" (some other frame makers use a larger size.)

                      A:

                      NO! 1 1/4" nominal i.d. schedule 40 and schedule 80 aluminum pipe is 1.62" o.d. (approximately 1 5/8"). 1 1/2 inch is just too fat for the standard 1 5/8" NRS 'U" bolts.
                      As an alternative to NRS fittings; the Hollander Mfg Speed-rail/Nu-rail cast pipe fittings can be used, but although speedrail fittings are considerably lighter, these are not as burly as NRS fittings.
                      I have had my 1 1/4" or 1 1/2" corner Speedrail ("el") fittings precision welded to the front and rear cross bars, and then have added a second allen screw on the side bar for security.
                      REGARDLESS of what you use, exact torque on bolts and allen screws is required. I use a socket drive 3/16" allen head to tighten the fittings: and I check the torque after an hour or so of rowing along.

                      I would say no. They're a tight fit around the NRS pipe.

                      Tom, they will only fit around our 1.625" pipe and smaller diameter pipe.

                      Click on the sizing tab under the picture.
                      2" ID. Shorter ones are for lo-pros, longer ones for attaching seat plates and such.

                      According to the NRS on line catalog they are 2 1/8" inside length by 2" wide for the standard and 2 5/8" inside length by 2" wide for the oversize.

                      They fit around the 1-5/8" standard NRS frame tubing and are 2-1/2" tall. The answer is also stated in the online catalog.
