Independent shopping perspective
PRT-952-216 is a six-piece set of standard Ratio InvisoMatch installation plates for Ratio Tuned Machine Heads. Each chrome plate has a 45-degree screw-hole mount designed to meet the existing machine-head screw position on the guitar. That makes the set relevant when the tuner installation needs this angled screw layout, keeping the mounting choice focused on the screw pattern already present.
