Micro-Mark 커플러 게이지 HO 표준 게이지용

Finally, a gauge that checks the knuckle and trip pin height too, not just the coupler. Solved a persistent uncoupling issue on three of my older cars almost instantly.

Used it on every car on my layout and the trip pin check alone saved me from two spotted derailments that I’d been chasing for weeks. The gauge’s machined steps make it dead simple to see where the knuckle sits relative to the railhead.

Finally, a gauge that actually checks the trip pin height instead of just the knuckle, so my locos stop false-coupling on switches. It’s solid metal and fits the NMRA specs perfectly, and I’ve used it on every car I own now.
