【Robust Large Padlock for Indoor and Outdoor Use】Diyife heavy-duty large padlock uses a one-piece lock body, 304 stainless steel lock bar, 52mm wide lock body, 304 stainless steel shackle, 8mm in diameter, weight 270g. The maximum security combination lock is designed for indoor and outdoor use, such as gates, garages, sheds, fences, storage, schools, gyms, staff rooms, etc. Provides better protection and security against theft. 【High-Quality Weatherproof】The waterproof combination padlock is made of high-strength zinc alloy, rust and weather resistant. The padlock is constructed with a zinc body and reinforced bumper for strength and reliability, and a hardened 304 stainless steel shackle for cut resistance. It has been tested over 180 hours in salt spray to prove its resistance to harsh conditions. 【4-Digit Combination Lock】Unlike a 3-digit combination, it offers 10,000 code combinations, which is more difficult and secure than the previous version. In addition, the 4-position metal code wheel on the bolt of this lock is strong enough not to be removed or broken by human force. You no longer have to worry about security! 【One-Touch Design】The cabinet padlock has a unique appearance and is practical and ritualistic as the hook can be pushed out by pressing the center button after the 4 codes have been set. 【Anti-Error Design with Hidden Password】The password is at the bottom of the lock, which improves its concealment. To change the password, you must loosen the screw, push up the SET key to display the SET key, and then reset the password. This can effectively avoid the problem that the password cannot be opened due to accidental password change.
