This is the back/butt feeder rest in the Quartix range from Middy, totally custom designed from scratch and developed over many months. Your rod will naturally sit in the top V of the design when you have your hand on the rod, or press the handle of the rod down into the rest and it will grip super tight (ideal if you're just about to open your flask or look at your phone). The rest is supplied with two change-over inserts to accommodate different size rod handle/butt diameters, so just about every feeder rod on the market will be compatible - genius! Featuring a secure brass thread and soft flexible TPE rubberised inner, it's also a compact overall size. There is a Quartix front rest version available as well, to complete your setup.
