Features: Easy to Operate: Two different ends a longer pointer and a larger pulley. The pulley slides smoother the pointer can be adjusted and retracted and can penetrate deeper contours for sliding and drawing. Design: The blue contour gauge has a pulley end that can be pulled smoothly reducing friction loss and protecting the surface. The pointer end is designed to be retractable and the convenient extension design makes it easier for the contour gauge to measure deeper. Precision: The pointer can be locked by tightening the screw handle to prevent it from loosening affecting the accuracy of marking and avoiding affecting the accuracy of copying and drawing lines. Locking Pencil: The newly upgraded blue contour gauge contour tool can easily lock pencils. The screw is a plastic thread that causes significant friction when turning the screw handle. The hole for inserting a pencil is fan-shaped making it easy to lock the pencil. Wide Application Range: Made of ABS plastic and metal it is tough resistant to falling and durable. It can easily replicate various shapes. Very suitable for installing tiles laminated materials carpets checking dimensions etc. Specifications: Material: ABS+metal Size: 220mm * 35mm * 25mm Notes: 1.
