The triangle key lock is a common lock in industry. It is named after using a triangle key. Triangular key locks are usually installed on rail transit (e.g. trains, subways, buses) and cabinets to protect the security of cabinets and some equipment.

Thanks to the stability and pressure resistance of the triangle, the triangle key lock is not easy to deform in the process of unlocking and is more stable and durable than other locks. In addition, this lock only needs to be rotated slightly in the process of unlocking, so the operation is simple, saving time and labor.

Secondly, the triangle key lock has a unique advantage, namely convenient management. In general, this lock has a uniform shape and does not need the key bitting. Therefore, one triangle key can open any triangle key lock. When workers need to manage and maintain the cabinet, they can open any triangle key lock with only one key instead of a bunch of keys, which is very convenient to manage.

Besides, Make triangle key locks are made from zinc alloy. The lock case and lock cylinder are made from stainless steel, and the surface is treated with bright chrome.

In addition, some of Make triangle key locks are specially equipped with dust caps, which can be waterproof and dustproof. The key is made from high-strength and high-quality zinc alloy, which has wear resistance and light torque, ensuring the firmness and durability of the triangle key lock.
