1. Sponge Handle The hammer's sponge handle effectively absorbs impact and reduces hand vibration, while its nonslip surface ensures safer operation. Its ergonomic design provides comfort even during prolonged use. Additionally, the handle absorbs sweat and moisture, keeping hands dry and preventing slippage, thereby enhancing work efficiency. 2. Stainless Steel Body The hammer's thickened stainless steel body ensures stability and resists deformation and wear. It is corrosionresistant and rustproof, even in wet conditions. The chromeplated ball head features a smooth surface that leaves no marks when testing walls, protecting their finish. 3. Double Pressure Groove Design The ceramic tile tester's double pressure groove design ensures a stable connection for the stainless steel rod, improving detection accuracy. It enables smooth, effortless pulling without jamming, enhancing ease of use. The 360° reinforcement with eight rivets (for the 130 cm / 51.18inch model) secures the ball firmly, preventing detachment during use. 4. Adjustable Telescoping We offer two models of this stainless steel rattle hammer: one with a maximum extension of 130 cm (51.18 inches) and another reaching 200 cm (78.74 inches), catering to different scenario requirements.
