What this tool does and why you need it Holds your tape measure securely in place with a toe plate that prevents slipping, so you get repeatable, precise toe measurements even when working alone. Speeds up alignment checks and adjustments by combining the accuracy of caliper-based measurement with the quick setup and comfort of a string-measure method. Key benefits Accurate single-person measurements: Toe plate design keeps the tape steady for reliable results without a helper. Faster control-arm/toe adjustments: Set toe precisely and efficiently, reducing trial-and-error and saving time on alignment work. Improves vehicle stability: Precise coaxial distance readings of wheel measuring calipers enable targeted adjustments that help restore correct tracking and handling. Broad compatibility: Designed for use on a wide range of passenger cars, motorhomes, and SUVs; includes multiple hole patterns to fit various bolt circles for greater versatility. Main features Toe plate secures tape measure to prevent movement during measurement. Multiple hole/bolt patterns to accommodate different wheel and hub configurations. Purpose-built for measuring coaxial distance of wheel calipers for accurate alignment input. Enables precise toe-in adjustments with the convenience and speed of string-measure techniques. Practical applications (use scenarios) After replacing tie rods, control arms, or wheel bearings: verify and set toe quickly on your driveway or in the shop without specialized alignment equipment. Custom wheel or bolt-pattern work: use the multiple hole patterns to adapt the tool to different bolt circles and confirm correct coaxial alignment. Routine suspension maintenance for SUVs and motorhomes: perform fast, accurate checks and corrections to maintain straight tracking and improve road stability. Who it's for DIY mechanics and car enthusiasts who want accurate, single-person alignment checks. Small shops and mobile technicians needing a compact, adaptable tool for quick toe and caliper-distance measurements. Owners of passenger cars, motorhomes, and SUVs looking to ensure proper toe settings and handling performance. Performance and usability Simple to use: secures tape, aligns with calipers, and allows straightforward adjustments. Versatile fit: multiple hole patterns increase compatibility across vehicle types. Designed to deliver precise measurement inputs to help you make targeted alignment corrections and improve driving stability.
