TPU Door Stopper – Security Purpose This item is a TPU-printed door stopper specifically designed for police and security use. Its purpose is to keep doors from closing during operational procedures, allowing safe and continuous access to the interior of a room or building. Manufactured in flexible and durable TPU, the piece provides excellent grip, resistance to deformation, and reliable performance even under pressure. TPU’s material properties—elasticity, impact resistance, and anti-slip characteristics—make it ideal for maintaining the door securely open without damaging surfaces. Please refer to the TPU material specifications for detailed information on mechanical resistance, flexibility, and recommended operating conditions.
