We add the NRS Bighorn I Raft Frame to our raft when we want to increase its rigidity and lets us secure accessories. Whether we're attaching a cooler or a dry bag, this frame battens down the hatches so nothing escapes, even in rough water. Hot-forged LoPro fittings provide multiple adjustment points for the frame, and the anodized aluminum construction is sturdy without being unreasonably heavy. This frame is compatible with a number of NRS accessories for customizing our raft however we please. The Bighorn I comes with two side rails, a one-foot bar, three crossbars, one low-back seat, one seat mount, two 8-inch oar mounts, and two 9-foot straps with strap slides.
