The precision contour gauge measures uneven object contours accurately and quickly with 1.4 mm narrow tracing pins. A practical locking mechanism on the handle prevents the rails from slipping while marking on the desired material. The contour gauge eliminates the need to create cumbersome templates when laying laminate, parquet, tiles, vinyl, PVC, or carpet. An integrated scale with centimeter and inch markings ensures maximum accuracy during installation work. With a high measuring depth of 124 mm, the duplication gauge allows for measuring large contours. The dimensions of the two profile gauges are as follows: one handle length of 300 mm with rails measuring 130 x 250 mm, and another handle length of 185 mm with rails measuring 130 x 130 mm. It is rust-resistant and durable, made from robust ABS and PS materials.
