The SPI 91-348-3 is a single-end feeler gage holder designed to securely grip and organize feeler gage blades during precision measurement work. This holder is compatible with feeler gage blades that are 0.5 inches wide, providing a stable grip for consistent, repeatable gap and clearance measurements. Weighing 0.25 pounds, it is a lightweight, handheld tool suited for bench and field use. Machinists, engine technicians, HVAC technicians, and maintenance professionals rely on feeler gage holders to protect blade sets and improve measurement control during service and assembly tasks.
