Find answers to the most common questions about the ABLOY 340 Padlock, its applications, security features, and suitability for various environments.

What is the ABLOY 340 Padlock?

The ABLOY 340 is a Grade 4 high-security padlock engineered to protect high-value assets against determined physical attack. It combines a case-hardened steel body, a 10 mm case-hardened boron steel shackle and ABLOY's unique rotating disc locking technology to provide exceptional resistance to cutting, sawing, drilling, twisting and picking. Trusted throughout New Zealand's forestry industry, farming, critical infrastructure and industrial sectors, the 340 has earned a reputation as one of the toughest and most dependable outdoor padlocks available.
