Questions & Answers

I’m looking for a narrow level that will fit in a crevice, preferably under 1” width. The dimensions on the site don’t make sense to me, saying the width is over 13”. Can someone confirm the dimensions of this level? Thanks

Answer This Question

Does the digital readout work for the full 40"? If I'm leveling something that's 32" long, will the digital display show an accurate reading?
ByAug 24, 2024
1 Answer | 
Answer This Question

This question refers to the digital readout on the torpedo level included in the 2-piece set. The extendable box level itself does not have a digital readout. The digital torpedo level is 9" long. Therefore, it would not provide a digital readout for the full 40" of the extended box level. However, if you are leveling something 32" long, you can use the 9" digital torpedo level to check the level at multiple points along the 32" length.

    Yes. It has a magnetic strip running down the long edge (bottom I think). We keep our 12” & 10” versions of this level stuck to the side of our garage fridge for quick access.

                  All bubble levels should have the bubble centered in the vial. This level has a feature that helps determine how far out of level the object you are checking. The markings allow you to adjust the object to level be suggesting how far out of level it is. The level is only one foot, so if you are working with an object that is several feet long, the actual adjustment will be greater than what is listed on the vial. This is my favorite level when working with small objects such as drawers and drawer slides, as well as door adjustment with European hinges.

                  Really nice level. I love the one foot levels, and empire true blue are well made, easy to read, and accurate. I also have a four foot true blue level, and it is my go to. Purchase without hesitation, and you will not be disappointed.

                  I tried to borrow a level from a neighbor for a project, leveling a bronze bowl (birdbath) atop three stones, leaving an under space for lizards. No luck. So I bought this level. Perfect size, surely I’ll use it again.

                  Broke after two days. The 12 inch level fell out of my tool belt from a total of 4 feet above the driveway and this poorly made tool shattered into 3 parts.

                    Two separate levels, don’t work together. Disappointed
                    From the item description I got the impression that the short digital level somehow attached to the longer extendable bubble level. This is not the case unfortunately! Otherwise they seem well built and I like the extendable feature on the longer unit - but it would be way more useful if they worked together.

                      Great level
                      I've had this level for over 2 years and it's usually the first one I grab when I'm choosing between the three that I have. It's very accurate at all angles. It is lightweight and the magnet is a plus since it's not too strong. There isn't anything that I dislike on it so far and it does meet my expectations. Please hit the thumbs up if this was helpful.

                        Empire has done it again! They have come out with a 48" box level that extends up to 78 inches. Crafted of finely machined hard tempered aluminum. Highlighted with a white viewing ring, their trade mark blue colored level tube making the bubble easy to read. The extension can be set at any length up to 78 inches and locked in place with a set screw. Extension bar is raised approx 1/16" for easy scribing and marking. Storage end cap is easily popped out for precise measuring.

                        OK - I admit I am a tool junkie. But I find that this level fits a need for me. My home was built in 1906. It has 76" doors. The house has settled over the years, and some of the doors are out of plum. So I need to re-shim the jams. With modern doors, I can use my 78" level. But it is too long for the old doors. This level expand to the length of the jam, letting my shim it plum and even. Sure, I could use my 6' level and move it to cover the part of the jam I am working on, but having a level that goes the length of the jam makes things a lot easier. I am sure it will see more uses in the future, but it is definitely filling a current need. As an added bonus, it is easier to store them my 6' and 78" levels!

                        This is a review on a 24 to 40 inch expandable box type aluminum level use it a couple times so far seems to work rather well just wouldn't think you don't have enough links on it you can extend it out to 40 inches and it dusty pretty true the whole way through I'm I'm really impressed with it I would recommend this to anybody that is replacing the box level looking for something to give you a little bit of expansion that works great on doors would recommend

                        Overall I’m happy with the product but my biggest complain is that it’s not magnetic like the rest of my Empire levels. I do like how there is measurements on the level when extending. Extends nice, level works good. Weight is not bad, it’s not light, I think my 6’ might weigh less actually but still I’m happy with it and would recommend it. I wish they made it magnetic though.
