The engineer and architect scale tapes are the new standard for scaling plans in the field or office. One of the main problems with triangular rules is that they cannot easily be taken out on a job site or carried in your pocket. The engineer scale tape has all of the 10, 20, 30, 40, 50, 60 scales you'd find on a standard engineer rule. Included in the architect scale tape you'll find the following scales: 16, 3, 1 1/2, 1, 1/2, 1/4, 1/8, 3/4, 3/8, 3/16, 3/32, and 1/16.
