Sound Detection Hammer, Ceramic Tile Hollow Checker, Inspection Tool

The length of the telescopic hollow drum hammer can be extended to 130cm, allowing for flexible detection distance. The joint incorporates a double groove design to prevent shrinking during use, ensuring a tight and stable connection without any shaking. Adding rivet reinforcement at the connection between the ball and the pipe body effectively reduces the movement of the ball, making it more durable and stable. The sponge handle is made with high-quality materials to provide a comfortable grip. It allows for longer periods of use without sweating or experiencing unpleasant odors. The product becomes compact and easy to carry with a length of 25.5cm after shrinking. The package includes a lanyard, which can be attached to the wrist to avoid dropping.
