The LoPro Fitting is the heart of the NRS frame system, allowing you to configure your frame however you choose. Now in hot-forged aluminum, they're stronger and lighter with a polished, streamlined finish.
  • The NRS LowPro Frame fitting secures cross members and frame accessories to our 1 5/8" OD frame pipe.
  • Forging the aluminum aligns the crystalline structure of the metal, creating a much stronger LoPro than the older, cast version.
  • Because of that extra strength we're able to slim down the profile and hollow the shank, making it 25% lighter while still being stronger!
  • Molded ridges on the gripping surface provide increased holding strength on high-torsion frame accessories like casting platforms, thigh bars and deluxe foot bars.
  • The LoPro fitting includes a coined (flattened curve) U-bolt, two washers and two nylon lock nuts, also a 5/16" x 2" bolt and nylon lock nut for attaching the LoPro to frame pipe.
  • If you're swapping out the new forged LoPros for the older cast ones on your frame parts, be aware that the LoPro will not have holes drilled for the bolt that affixes it to the frame pipe.
  • NRS frame parts that include LoPro fittings are manufactured here by our skilled Frameshop craftsmen, using specialized lathes, jigs, hydraulic benders and drill presses. For best results we recommend that you only attempt assembling your own frame parts from frame pipe and LoPros if you have good metal shop skills and equipment. If you have specific questions, please give us a call.

    • NRS LoPro Frame Fittings

      Q:

      What is the measurement from the inside edge of the shank to the center of the saddle mount. To ask another way, if I have a 60" wide frame and am cutting a piece of tubing to use with the LoPro's what length would I cut the tubing so that after adding a LoPro on each side the assembly would fit the 60" frame?

        A:

        You'll need to take 2- 2 1/16" off each side to accommodate for the Lo Pros.

        A:

        Yes. They will work fine. I put the new ones on my frame and they look great. Update you oar towers to the new ones and you will have a great looking frame.

        A:

        They would probably fit, but we can't be sure. Remove a couple of your LoPros and carefully measure the inside diameter of the pipe. The shank on these new forged LoPros will fit very snugly inside 1 5/8" inside diameter pipe. Back when your frame pieces were made the ID of the pipe we bought varied slightly, so we lathed the LoPro shanks to fit. We've now purchased our own pipe dies that the pipe manufacturer uses, so we have that consistent 1 5/8" inside diameter. Give us a call, 800.635.5202, if you have questions.

      Q:

      Well, you say they are 25% lighter but don't specify the weight in the specs. So what do they weight and what do the existing LoPro's
      weight? Also you should mention that they will only fit 1-5/8" diameter schedule 40 aluminum pipe. The schedule of the pipe refers to the wall thickness as I'm sure you know.
      The new LoPro's do look great. I just order a new style 8" oar stand and you finally put in a plastic bushing, right on!!!

        A:

        JV, the new LoPros weighs 11.6 ounces. The old ones vary in weight, about 15.3 - 15.5 ounces. They are cast in sand molds, which leads to slag and protrusions that have to be ground off. Factory run pipe varies in inside diameter, so we often had to lathe the LoPro shanks to fit. Since the shanks on the new model are precise we've purchased our own pipe die that the pipe manufacturer uses, so we get a good fit. And yep, the nylon bushing, an idea that Bill Parks came up with, is a great addition.

          Comments about NRS LoPro Frame Fittings:

          The 4 fittings I drilled were virtually identical. No longer will I need fittings for every piece of tube I own. I will Drill all mine in the future to maintain a 1.400" bolt spacing from the lip. Had to add a couple of undersized drills to insure the backside hole didn't walk off.

                Comments about NRS LoPro Frame Fittings:

                My old lopros slipped on my fishing thigh bars. The new lopro is very tight. Good grip. There are no pre drilled holes. They should have included this in the product description. It cost me $26 to have the holes drilled in 3 lopros at a machine shop.

                I love these new lopros! They are exactly as advertised except they left out the sexy factor. The only bad thing is now I want to swap out my whole frame to have all new fittings. As always it is a pleasure ordering from the great folks over there at NRS.
