The Abtus ABT4060 Sighting Board set provides a popular, quick, and accurate method for measuring vertical alignment, making it especially suitable for repairs and lifting in areas affected by subsidence. The three boards feature heavy-duty spring grip rail feet and integrated spirit levels to ensure vertical accuracy.
The intermediate board adjusts up to 24mm of lift in 0.25mm increments, while a spring-indexed system enables further measurement up to 160mm in 5mm increments.
The translucent target board allows visibility in all daylight conditions and offers the option to fit a backlight for use at night or in tunnels. Constructed from nylon, acetal, and GRP, the boards are lightweight, robust, and electronically non-conductive.
