A great deal of the measuring and marking that we do as woodworkers is within two inches of a board's edge. We mark for rabbets, dados, loose tenons and all manner of joinery. And many of the measuring and marking tools we reach for are a bit large and unwieldly for the job at hand.

Infinity Tools has the answer to your simple measuring and marking needs.

Made on accurate C.N.C. machining centers from high quality aluminum billet, our Pocket Marking Rule works as a saddle square, and also lets you exactly reference 32nd of an inch detents up to two inches from a board's edge. We black anodize the body and laser engrave 1/16" graduations for easy reading and guaranteed precision. Insert a freshly sharpened pencil and slide the rule along the edge. It's that easy!

Start, stop and index with all the finesse you need in your shop.

Our Pocket Marking Rule will quickly become an always-out member of your benchtop tools!

How far from the edge can it measure?

The rule lets you reference measurements and exact 32nd-of-an-inch detents up to two inches from a board's edge, which covers most edge-joinery layout tasks.

What material is the T-square made from?

It's machined from high-quality aluminum billet on accurate C.N.C. machining centers, then black anodized for durability and a clean, glare-reducing finish.

What size are the graduations?

The body is laser engraved with 1/16" graduations for easy reading, plus 32nd-of-an-inch detents for finer indexing.

How do I mark a line with it?

Insert a freshly sharpened pencil into the desired graduation, set the saddle over the edge of your board, and slide the rule along the edge to mark a consistent line. It's designed for quick start, stop, and index marking.

Does it work as a saddle square?

Is the finish durable?

The body is black anodized, a finish that protects the aluminum and resists wear, while the laser-engraved graduations stay legible through shop use.

Why choose a pocket-size square over a full-size one?

Many measuring and marking tools are large and unwieldy for close-to-the-edge work. This pocket rule is sized specifically for the marking you do within two inches of an edge, so it's faster and easier to handle for everyday joinery. See other measuring & layout tools.

Who makes this marking rule?

Is it accurate enough for fine joinery?
