The Sealey GA50 Laser Wheel Alignment Gauge is a professional diagnostic tool designed for checking wheel alignment on cars and light commercial vehicles. This optical system uses a low radiation laser beam to accurately indicate toe-in or toe-out measurements, making it an essential piece of equipment for garages, workshops and mobile mechanics. The single leg configuration with reversible contact probes allows for convenient on-ramp use, eliminating the need for a dedicated alignment bay. The gauge accommodates rim diameters from 200mm (8") to 600mm (23.5"), making it compatible with most passenger cars and light commercials. Powered by 2 x AA batteries (not included), the Class II laser system offers a measuring range of +/- 2 degrees with a beam height under 50mm. The momentary operator pressure switch ensures the unit powers off when not depressed, helping to maximise battery life which typically lasts between 6 to 12 months depending on usage frequency. Operating instructions are included to ensure accurate alignment checks from the first use.
