Hiding in Plain Site

Earlier this week I found this hanging in the boiler room.

I┬áreplaced the thermocouples on my boiler and hot water heater in the last few years. Would have saved a trip to Home Depot if I had noticed this at some point in the 10 years I’ve lived here. Price is a bit different from the $13 I paid for a thermocouple last December.

Makes me wonder what else is hiding around the house.
