ULTRA SQUARE TOOL TEST BY
BUILDER MAGAZINE

The idea. The manufacturer says builders can use the tool for laying out simple and complex angle cuts, doing quick center-line layouts, and marking multiple-thickness members quickly.

And it claims that one of Ultra Square's strong points is easy framing layout. To pull layout, framers can clip their tape onto the vertical guide and slide the tape and tool along the plates (or rim joists), marking along the square's edge at each layout point.

The square is designed so framers can mark single, double, or triple thicknesses of built-up framing members without repositioning the square.

Test results. Here's what our tool testers said about Ultra Square after trying it out on site:

Ace's framers liked using the tool for wall layout (especially for jack and king stud layout) and said it's great for transferring marks from one board edge to another. * However, they complained their tapes didn't clip on well for pulling layout -- only the Stanley tapes worked this way -- and when they did work, the tapes' blades got in the way of marking layout lines.

Some testers wished the tool had more degree markings for going around bays and fireplaces. And because of its shape, Ultra Square is slower than its triangular competitor -- Speed Square -- for marking 45-degree angles.

But the testers said Ultra Square is faster than a framing square for rafter work, and they gave the tool high grades for laying out all sorts of roof pitches and bird's-mouth seat cuts.

Ace Carpentry's president, Anthony Clatterbuck, suggests the tool works best in the hands of an experienced cut/layout carpenter.
