Good product
Work as designed, but not American made and now there are other options on Amazon including a four pack for not much more. I bought one of the tall sets also and these fit on the tall sets included holder if you like those carabiner holders.

The old standard
I have owned several stair guages throughout my career. They are always sold in pairs, so I am not sure why they call it a "2-pack" as just one guage would really work on a framing square. But these are made well, and because they are brass, they should work well for several years without any worry. Just don't loose them. They have been the same for at least 20 years. The only thing I would like better, is if the thumb screw was more of a "wing-nut". I like to make sure they are on the square really tight, so I usually tighten them with a pliar or vise grip before a start to do a lot of marking.

Fond memories of these with my dad.
Love this. My dad had these when I was growing up to make stairs.

Elegí esta valoración porque es una enorme ayuda en múltiples tareas en el ámbito de la carpintería tales como marcar zancas de escalera, los ángulos de las vigas y largueros en tejados,etc. El producto es fuerte y no hay que andar con el entre algodones, se lo recomendaré a mis compañeros de taller.

Die beiden Winkelanschläge sind sehr schön verarbeitet und man kann Winkel bis ca 5mm stärke damit bestücken. Hab mir mal welche aud einer Stahlmutter selbergemacht und damit den Winkel ruiniert. Messing ist wesentlich sanfter.

I needed to replace the stairs on my home and I looked up how it”s done by pros and learned about these items. I calculated optimal “rise” over “run” for the first time and attached these brilliant accessories to my framing square and was able to quickly trace out the number of steps and then cut them out as demonstrated. Highly recommended!
