    Check that your pulley, gear, or sprocket system is properly aligned. These magnetic lasers stick to equipment made of steel. Project the laser beam down your belt or chain and look to see how it hits the target—you can determine angular and offset misalignment at the same time. The target has a machined surface that sits parallel to the contact surface for precise alignment. Adjust your setup until the laser line overlaps with the reference line on the target. These lasers are portable and battery powered, so they’re easy to use in spaces without outlets.
    Red Laser—Red lasers are best for indoor environments, since they’re dimmer than green lasers.
    Green Laser—Green lasers appear up to 10 times brighter than red lasers, so they’re easier to see outdoors or in bright indoor lighting, as well as from far away.
    Built-In LED—Lasers with a built-in LED provide light in dim areas.
    One Adjustable Target—Lasers with one adjustable target have a single laser line that indicates offset and angular misalignment. A mirror on the target reflects the laser back to the transmitter’s reference line to show misalignment. No need to fuss with the traditional multi-target method.

    Slip this laser into your pocket so it's on hand to align belts, pulleys, chain, and sprockets. Place the tool against the side of your pulley or sprocket and project the laser onto the included target to detect angular or offset misalignment. They mount magnetically, so you don’t need any fasteners to secure them. The surface of the laser is machined, so it sits flush against flat surfaces for easy and precise alignment. They’re powered by a disposable battery, so they’re portable.
