Ideal for contractors, builders, architects, engineers, and other serious building professionals, the Construction Master 5 Construction Calculator (model 4050) from Calculated Industries helps you get fast, accurate construction-math calculations within the place of job or at the job website online. Reduce the risk of expensive errors when estimating costs and materials. Enter the numbers–just as you might say them–and the solutions appear instantly.
The Construction Master 5 works in and converts between building dimensional formats: yards, feet-inch-fractions, decimal feet-inches and metric–including area and volume. A custom rafter function provides common rafters, regular and irregular hips, valleys and jacks, even as a rake-wall function determines stud length for any on-center spacing, in ascending or descending order. Other dedicated functions include stair calculations for risers, treads, stringer length, and incline angle; solutions for circles, arcs, columns, pillars, windows, post-holes, and more; and board feet lumber estimations.
Other features include solving for cost per unit, a “paperless” tape that allows you to review the previous 20 entries to double-check your totals, ability to store preferred fractional values and dimensions, and work with standard calculations.
It’s powered by a single CR2016 battery (included), and the Construction Master 5 has an auto shut-off feature that turns the calculator off after about 8 to 12 minutes of non-use. The calculator measures 2.95 x 5.7 x 0.67 inches, weighs 4.5 ounces, and comes with a hard protective cover with a pocket reference guide. It is backed by a one-year limited warranty.
