Metal Escutcheon Ring Slant Processing Set Red Color Guitar PRS etc. This is an escutcheon ring in a color that seems like it should exist but doesn't. It has a good thickness, and the top surface is arched, which also suits PRS guitars. In fact, you might even think it was made for PRS guitars. Also, the front and rear are made with different thicknesses, and slant processing (inclination) is applied. The bottom is flat. I have it on my PRS, but it should fit guitars that can also use commercially available escutcheons, so the standard itself is probably standard. Thickness (approximate dimensions) Front Center 4mm～6mm Both ends 3mm～5mm Rear Center 6mm～8mm Both ends 5mm～7mm
