Stainless Steel 3050-M Metric Traveler

The 4560-M Metric Master Framer and 3050-M Metric Traveler stainless steel framing squares feature the same expansive patented rafter tables found on the 1824 Master Framer and 1218 Traveler—only specified by the degree of roof pitch. They each allow for the same unprecedented layout versatility, quality, and precision. Chappell Universal Metric Framing Squares will help you make every project a masterpiece.

Forgot your calculator at home?
No problem, the Metric Master Framer & Metric Traveler have you back!

No problem! The Chappell Metric Square‘s got you covered. All you need is a pencil and a scrap piece of wood to make simple arithmetic calc’s on-the-fly.

Don’t know how to use CAD?

No Problem!—The Chappell Metric Master Framer allows you to get right to work actually building. No need to know CAD, and No time wasted teasing your mind in abstract thought. All rotational angles and length factors are deeply etched into the body and blade of the square.

NO BATTERIES REQUIRED
