8 Pcs Hanging Bubble Line Level String Level Tools, Used for Building Trades, Surveying, Engineering, Metalworking and Equipment Measure

These strong levels were low cost, easy to use, and were perfect for our project

It's good for small works.

The Reason for Selection:These simple devices are always handy to have around for various projects. One of my uses will be to help with hanging a camping hammock at comfortable angle. I like the foot end to be about a foot above the head end. That works out to 4-7 degrees. Perfect for this device since a 5 degree incline has the bubble just touching the outer rim of the tube.General observations:The devices are light weight and the frame is of good quality ABS type plastic. Hang this device on cordage that is 3mm (1/8") or smaller. If the 3mm line is very taught, you will have difficulty with putting the device on the line.I spot checked the bubble levels with the level app on a phone. I know it's not a NIST traceable measurement device, but it is what I have. All copies of the product had the bubble inside the lines with the phone test.I lined all the copies up on a table to see how they compared to each other. They are all in the "good enough" realm as far as I am concerned but there is diversity in the indicators.I took one level apart to test how well the bubble tube is attached to the frame. It is bonded on one side, the entire circumference of the tube. It is also bonded heavily on one side of the tube to the frame.The Good:The tube that has the spirit liquid is secure in the plastic frame. If the level is dropped, this will maintain the level to remain oriented to the plumb line of the plastic frame.The Bad:Nothing Bad.The Ugly:Nothing Ugly.Value for Price:From my perspective and experience, the price is fair.

I recently purchased the ABS Mini Bubble Level and have been extremely impressed with its performance. The level is made of high-quality ABS material, which is clear, precise, and easy to read. It is also equipped with a special molded hook that allows it to hang from a building line, making it easy to use in a variety of construction and engineering applications.One of the things I appreciate most about this level is its easy-to-read design. The hollow plastic housing allows me to read the line level from the top, side, or bottom, and the lightweight design helps to reduce line sagging for accurate readings. The open type of the level also allows it to slide freely along the lines, which minimizes dropped calls.The wide application of this level makes it a useful tool in the bricklaying, plumbing, gutter, and tile construction industries. It is also great for engineering measurement equipment and angle balance measurement. The V-groove design at the bottom is an added bonus, as it provides reliable placement when leveling round items such as pipes, conduits, and shafts.Overall, I would give the ABS Mini Bubble Level a rating of 5 stars. It is a high-quality, easy-to-use tool that is perfect for a wide range of applications. The clip on the level allows for easy carrying and storage, and the V-groove design is a great feature for leveling round items. I would highly recommend this level to anyone in need of a reliable and accurate tool for construction and engineering projects.

I am impressed with this simple level tool. I tied a string real tight from one side to the other of my 24' pool wall and hung this bubble line level in the center, to level the pool. It was easy to use. My pool was only approximately one inch off after filling it with water. The accuracy isn't perfect for long stretches but close. I found that the trick is to make sure the string is taught from point A to point B.

This is a good set of 8 levels, just not quite as good as the metal ones. Still, for the price and the convenience of having 8 levels, this is a good value. Little line levels are always misplaced or lost, so having 8 really makes up for the shortcomings compared to the aluminum ones. These plastic ones are lighter, so they don't slide and track as well on a string, but it is a small shortcoming compared to not having one at all. These plastic line levels are as good as any plastic ones I have used. With a set of 8, I was able to compare them and they all produced the same results. That is pretty good quality control.

For the price and getting eight levels great buy the accuracy not there at all. If you need something precise, just buy the Johnson but if you’re gonna lose these in a day or two, definitely well worth the money.

I feel like a fool. I never even knew that these line levels existed until I stumbled across the listing on Amazon.Up to now, I have been trying to find a level for laying concrete flower bed edging using a line with a regular level held just above a taut line. Well duh! These little individual levels simply clip onto the line and show you immediately if you have it level or not. It's so fast and easy that it feels like cheating!They are lightweigh and, so long as the line is kept taut, they won't depress the line and will give you true level. The bubbles and scale are easy to see in the window and being bright orange means that they are unlikely to vanish in the dirt or, at least, will be easier to find when they do.Why do I feel like I was the last person alive to know about these. 25 stars! Okay, 5 stars it is..
