Product Details

The LoPro™ Fitting allows you to easily configure and customize your frame. Made from hot-forged aluminum alloy for a strength-to-weight ratio that can't be beat, this streamlined, polished piece of hardware is the heart of the NRS frame system.
  • 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.
  • When using LoPros with non-NRS pipe, the pipe needs to be 1.380" inside diameter. Also, be aware that the LoPro will not have holes drilled for the bolt that affixes it to the frame pipe.


Product Tips

  • NRS frame parts that include LoPro fittings are manufactured by skilled Frameshop craftsmen, using specialized lathes, jigs, hydraulic benders and drill presses. The LoPro does not have the hole drilled for attaching it to frame pipe. For best results, we recommend only attempting to assemble 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.
  • Stainless steel bolts and nuts are especially subject to a condition called "galling," where their surfaces bond together so tightly they can't be separated without breaking the bolt. The chrome-plated lock nuts and washers we supply don't cause this galling. If you choose to use stainless steel nuts, apply an anti-seize lubricant to the bolt's threads before tightening the nuts.
