If you are setting your tripod up on a smooth, flat surface, a triangular frame should be used to secure the legs.If your tripod is being set up on a surface such as finished concrete or tile, it is important to have a piece of non-slip material approximately 5' x 5'.In order to secure setting up a tripod on a slope, only two of the three legs can be downhill the other must be placed up the hill. Adjustable-leg tripods are the only option for uneven terrain.The surface the tripod will stand on determines how the tripod is set up so be sure of the conditions of the ground or surface where the tripod will be used. When choosing a tripod, worksite conditions are an important consideration. When attaching laser levels or other leveling devices to tripods, make sure to check the screws and bolts are not too loose or too tight.Make sure your tripod is clean and in working condition before attaching any instruments.Have the proper attachments available for the leveling device as well as the tripod (for example: a laser level detector or grade rod).Verify the level, laser level, or other instrument being used will fit the tripod.In order to properly use your tripod, you must: There are three different kinds of heads: If your laser level or other leveling instrument does not have a 5/8 inch thread, you will need to buy an adapter to convert it.

The head of the tripod is attached to the legs and allows a steady surface to connect leveling devices. Some tripods can be purchased with rubber attachments which prevents either of these from happening. When working outdoors, points on the bottom of the tripod are essential, but when working indoors, metal points can slide or scratch floors.
PointsĮach tripod, whether fixed or adjustable, has metal points on the end of the legs for added stability and can help provide a stable environment for the leveling tools on top of the tripod.

The most common materials for tripod legs are: Tripod ComponentsĪ tripod is made up of three Legs, each with metal Points called shoes and a Head, which the laser level or other leveling device attaches to. These tripods are being replaced more by the adjustable-leg tripod. The adjustable-leg tripod is also easy to transport due to having retractable legs.Ī fixed-leg tripod's legs remain the same length continuously. The adjustable-leg tripod is easier to set up on uneven ground because each leg can be adjusted to exactly the height needed to find level, even on a very steep slope. There are two different kinds of tripods: adjustable-leg tripods and fixed-leg tripods.Īdjustable-leg tripods are the more common of the two in the construction world, especially outdoors because of generally uneven terrain.

Tripods are portable and provide support and stability along both the side-to-side and up-and-down axis of motion. View tripods, detectors and laser accessories from Johnson Level.Ī tripod is a three-legged stand, important in providing the foundation for laser levels and other leveling instruments such as: rotary laser levels, line laser levels, dot laser levels, builder's levels, transit levels, automatic levels and even sometimes torpedo laser levels. A tripod is typically used with a leveling instrument, grade rod, laser pole and level detector. What is a Tripod? How do Tripods for Laser Levels Work?
