Can this be used in making precision markings or is it more for rough cut applications?

I do not feel this is to be considered a precision instrument. There are small bulges (drips), of paint along various edges that prevent one from being able to accurately draw straight lines or check an item for “square”.

How thick is this ruler?

The Mr. Pen ruler is about 1/16" inch thick and is made of a good quality metal. The metal is hard to bend and I personally like it.

Will this work at a Tshirt vinyl ruler?

I'm not sure I understand your question.

Is this ruler 1.5" wide?

The top portion is about 1.25 (the "top of the T") the longer part is 1.75" wide. Hope this helps

Perfect for layout of door jambs or window jambs

I love this square because it’s small enough to fit on my pouch hook and it’s great for tight layout of door jambs and window jambs. Recommend for all trades men doing floor layouts.

Muy buena regla T

Es un regla que superó la calidad que esperaba, es metálica y de una sola pieza por lo qur supongo que será extremadamente durable, incluso es pesada y tiene la medición en centímetros y en pulgadas. Definitivamente es un producto que si recomendaria para un adulto pues incluso es tan fuerte que puede resultar pesada para un niño.

Great for fab work

Bought this product because I seen another coworker with something very similar. That was just a little bit bigger than this one but overall I’m extremely happy it fits in my toolbox great and it’s great for metal fab layout.
