This authentic coverplate fits the standard Duolian and Triolian wood or metal body guitars that use a 9 1/2” resonator cone —incorporating a wooden “biscuit” bridge. Made of steel and richly nickel-plated, this coverplate features the perforated diamond pattern—also known as the “colander-style” coverplate.
