4560-M Metric Master Framer
3050-M Metric Traveler
The 4560-M Metric Master Framer and 3050-M Metric Traveler framing squares features essentially the same expansive set of patented rafter tables found on the 1824 Master Framer and 1218 Traveler. They each allow for the same unprecedented layout versatility, quality, and precision. Chappell Universal Metric Framing Squares will make every project your masterpiece—by putting a wealth of knowledge in the palm of your hand.
Like our Imperial squares, the Chappell 4560-M and 3050-M are not just squares—but powerful calculators—and NO batteries required!!! With only a pencil and a scrap piece of wood even the first-time builder will be able to lay out and cut the most complex, compound roof system.
Save Time—Make Money
Quality work takes time and costs money. With the Chappell Square you will save hours of time on each project simply because it will do away with hours of head-scratching. This allows you to get right to work and complete the job. Then you can get home to your family to finish the treehouse you promised to build with your kids—and this is PRICELESS! The time saved, and money made in the first day of use laying out your first compound roof system with the Chappell will likely be greater than the cost of the square. As a result, your kids will be happier, and that’s just the beginning!
Forgot your calculator at home?
No problem!—With the Chappell Square, all you need is a pencil and a scrap piece of wood to make simple multiplication and addition calc’s on-the-fly.
Don’t know how to use CAD to determine cut angles?
No Problem!—The Chappell Square allows you to get right to work actually building. No time wasted teasing your mind in abstract thought. All rotational angles and length factors for virtually any compound roof system are deeply etched into the body and blade, in easy-to-use decimal format. Therefore, it’s as simple to use as a connect the dots drawing for any preschooler.
NO BATTERIES REQUIRED
Coupled with the rugged 13 gauge 304 Stainless Steel construction, this square will last for scores of generations without ever needing a software upgrade or electric back-up system of any kind.
Just like the Sumerian cuneiform tablets, still legible after 6 millennia, there’s good odds the Chappell Square may still be around and functional into the next millennia as well. No moving parts, No maintenance, NO UPGRADES and NO BATTERIES REQUIRED. Not sure if the Construction Masters or Laptops will even make it into the next decade.
Whether it be a backyard playhouse or a scale-sized dollhouse for your daughter or granddaughter—or your own dream house—the Chappell Square will put the knowledge you need to build right in the palm of your hand.
