Swanson invented the Speed Square in 1925, and nearly a century later, it's still the layout tool you'll find clipped to a carpenter's belt on just about every jobsite in America. It's the rare tool that combines a try square, miter square, protractor, and saw guide into one rugged piece of cast aluminum—and it does each job well.
We use the 12-in Speed Square and the 12-in Combination Square for everyday layout, from squaring up sawhorses to marking rafters and checking joinery. Simple, accurate, made to last.
