Proline Alignment Kit is a visual laser system for checking and measuring straightness, flatness, squareness, parallelism, leveling and many other tasks. This kit combines the features of a transit, an infinitely long straightedge and laser alignment system all in one compact, portable, versatile product. Precision laser alignment for production, maintenance, and plant engineering projects, both large and small, has never been so easy.The Proline Laser produces a crisp, collimated laser reference beam that forms a bulls-eye pattern for easy visual alignment and precise measuring. This innovative laser is enclosed within a precision machined housing, ensuring that the laser reference beam is parallel to the side and base surfaces within 0.003 degree, or <0.030 inch at 50 feet. This level of accuracy is ideally suited for setting straight machinery runs, aligning production equipment, transferring mechanical points, locating shafts and bearing mounts, aligning belts and pulleys, and countless other industrial tasks.A finely ruled target and magnetic base are easily moved around for checking alignments, allowing one person to perform the work of several. The kit includes a leveling base so the laser can measure flat planes and machined surfaces. A 90 degree laser prism is useful for squaring machinery and checking the parallelism of rails, tracks and guides. A growing line of versatile targets, mounts and attachments expands the versatility of the Proline Laser and any task, however specialized. The Proline Laser and all of its attachments are stored in a durable carrying case for convenience and easy transport.
