Most likely, yes. The slot is designed to fit standard 1-inch wide tape blades, which covers the vast majority of professional and DIY tape measures (like Stanley, Milwaukee, DeWalt, etc.). The built-in rare earth magnets are strong enough to securely grab your tape measure’s metal hook, effectively acting as a "third hand" so you can measure long distances solo without the tape slipping off.

The "reveal" is that small, decorative step-back distance between the edge of your door jamb and the casing. The Trim45 allows you to set this distance anywhere from 1/8" to 1/2" (in 1/8" increments). Once you set your desired depth and lock it with the red button, the tool ensures every single corner of your door or window has the exact same spacing for a professional, uniform look.

While it’s famous for doors, it is equally excellent for window casing projects. Additionally, the tool features a built-in 45° angle head. This makes it incredibly useful for quickly marking miter cut lines on baseboards, chair rails, or picture frames without needing to grab a separate speed square. It’s a versatile marking guide for almost any trim work.
