The NRS Frame Deluxe Foot Bar utilizes LoPro attachment hardware to secure your foot bar to a frame crossbar, rather than the bar being attached to your sidebars like the NRS Frame Foot Bar. The advantage to this is that you do not sacrifice precious space that should be dedicated to a gear bay with a full length footbar. The Deluxe Foot Bar also has several pegs installed in the foot bar, allowing you to choose the height of your heels and gain better leverage depending on whether you are pushing forward on your oars or pulling back. One size fits most, at 32 1/2" wide!
Pro Tip: Depending on the angle of this footbar, you may have the LoPro attachment point rubbing up against a drybox or cooler. Try to keep the angle below 45 degrees to keep the LoPro hardware more vertical and out of the way.
