The Kapro 340 post level is a 5.4" x 7.6" spirit level with two level vials and one plumb vial with a sensitivity of "/inch for simultaneously determining the horizontal and vertical plane of posts, pipes, and beams. The vials are made of injection-molded acrylic to resist breakage. The level folds closed, opens flat, and locks every 15° to accommodate different pipe, post, and beam sizes to 6" in diameter. It has four magnets for attaching to metal surfaces and an elastic band for securing to non-metal surfaces, and is made of PVC (polyvinyl chloride) for impact resistance. Levels are used in the building trades, engineering, surveying, and metalworking, among other applications.
