The Double metal edges on this ruler Make it the perfect ruler for drawing building plans. The metals edges are easy to use for clean lines.

Got this for my kids for school and they have already used it several times. A simple ruler, good quality basic item. Works as a ruler should!

A must have in any office. This rule is great. The size makes it easy to store away in drawers and the price makes it easy to buy dozens at a time.

Received product in a very timely manor. Much higher quality than I expected for the price. Perfect for all the different plans I use! Will order form them again.

Super ruler. I like very much that it has metal edges, thanks to this, even after several months of use, I can draw straight lines. Definitely advise to everyone who needs to draw a lot

Akif I. on 06/14/2019

Love how this ruler has metal edges on either side, making it twice as efficient for drawing straight lines. It's also useful for measuring small objects, in inches or centimeters.

Vince S. on 12/20/2017

Made of wood with two metal edges, there is a 12 inch side and a 30 cm side to this ruler. By Westcott, this ruler can easily be used to measure repeats on fabrics.

Antonia S. on 11/25/2017

This is a pretty standard ruler aside from the double metal edges. The measurements are very easy to read and it's very high quality. Good deal.

Vivian B. on 10/23/2017

This ruler comes with a two sided metal edge, perfect for use with blueprints. The metal edge helps your writing implement slide across the ruler easily

Liz J. from Pancho's on 10/20/2017

The ruler has been great! Not only are the numbers easily identifiable, but the metal edges enable me to draw straight, easy lines. Perfect ruler for the price!

This twelve inch Wescott Flat Wood Ruler with Double Metal Edges was exactly as I expected. The standard size is one sixteenth and works very well. The metal edge feels solid without added weight and offers a no slip feature I appreciate. Very durable and would recommend.

keeping a straight edge is simple with this ruler. It has metal linings on both sides and provides for a guide for an accurate line drawing.
