Rated 4.5 out of 5 by 6 reviewers.
Rated 5.0 out of 5.0 by Keeping things straight Nice to have in the workshop for all measuring and drawing straight lines. Lightweight and easy to use. Hangs on the wall when not in use and so its easy to store. The numbers are bright and easy to read from either side of the ruler. It is very accurate with my tape measure. So I can go from one to the other without worrying about being off on measurements 1/16" or not. Strong and doesn't bend easy so you get straight lines every time. Its one of those "nice to have" tools in your arsenal of equipment to have in the shop. Good value Be Safe. February 28, 2015
Rated 5.0 out of 5.0 by Handy addition to my tool collection I have a 36" straight edge ruler but this one is better as it is 48". This is good if you want to draw a line or cut drywall that is 48" across. It seems to be well made, the divisions are well marked and it is not too heavy. It is from a company in Wisconsin but unfortunately it is made in China. It would be even better if it was made in Wisconsin. March 23, 2015
Rated 5.0 out of 5.0 by The most useful tool ever ... Its clear marks make it very easy to see and measure any lengths over 30" ... April 21, 2015
Rated 4.0 out of 5.0 by Better then a 4' level for marking. This is a nice length for marking across the width of plywood and paneling. I used to use a 4' level for that, but this straight edge works better. The thinner depth makes it easier to use. This is especially true if you are using it with a utility knife to scribe or cut material. The ruler marking are clear and easy to read. I am not sure how they will hold up under use, as they appear to be printed of, rather then etched into the metal. So if the printing wears off, there is nothing to fall back on. But it will still work fine as a straight edge. February 27, 2015
