This is the butt rest in the Quartix feeder range from Middy. Totally custom design, better than all others! Your rod will naturally sit in the top V-shape of the design when you have your hand on the rod, or you can press the handle of the rod down into the rest and it will grip super tight (ideal if you're about to open your drink or look at your phone). This butt rest will accommodate different size rod diameters, so nearly every feeder rod will be compatible - genius! Featuring a secure brass thread, as well as a soft flexible TPE rubberised structure to protect the rod. The overall size is very compact too.
