These sawhorses are portable, rugged and fully adjustable. They are great for filming video when an elevated track is required for dolly shots. The adjustable sawhorses have been tested in many different environments and have always performed extremely well. An advantage of this design is that they have the ability to break down, which means they take up less space when not in use and while in-transit. Another nice feature is the adjustability of the design, which allows you to set up a level track even if the ground you are working on is slanted or uneven.
