【Large padlock inside and outside, heavy duty.】Our large, heavy-duty lock measures 52 x 26 x 84.5 mm (L x W x H), has an 8 mm diameter chain, and weighs 270g. It features a one-piece locking body and a 304 stainless steel locking beam. This high-security combination lock is designed for both indoor and outdoor use, such as on doors, garages, sheds, fences, storage facilities, schools, gyms, staff offices, etc. It provides superior protection and security against theft. [Please note that the chain diameter must be compatible with your lock.]【4-digit combination lock】Unlike the 3-digit combination, it provides 10,000 code combinations, making it more difficult and secure than the previous version. Furthermore, the 4-position metal combination wheel lock is strong enough that it cannot be removed or broken by human force. You no longer need to worry about security!【High quality and weather resistant】The combination lock is made of high-strength zinc alloy, which is rust-resistant and weatherproof. The padlock is constructed with a zinc body and reinforced bumper for strength and reliability, and a hardened steel chain for cutting resistance. Its resistance to harsh conditions has been proven by over 180 hours of salt spray testing.【One-touch locking design】 This padlock has a unique appearance and is practical and ritualistic because the shackle can be ejected by pressing the central button after the 4 codes have been set.【Hidden password and error-proof design】The password is located at the bottom of the lock, which improves concealment. To change the password, you must unscrew the screw, press the adjustment button to reveal the SET button, and then reset the password. This effectively prevents the problem of the lock being locked due to an unintentional password change.
