JK312 cam lock stands out as our absolute best selling model. It consistently leads in sales volume year after year, earning the trust of manufacturers across many industries. If you are looking for a proven, reliable, and highly adaptable cam lock, the JK312 is the choice that thousands of customers have already made.
The JK312 is primarily constructed from premium zinc alloy, which gives it excellent strength and resistance to wear. The surface features a bright chrome plating that provides a sleek, mirrorlike appearance while also protecting against corrosion and oxidation. For projects that require a different look or a higher grade of material, we also offer the option to manufacture the lock in copper. This flexibility allows the JK312 to meet a wide range of industrial and commercial demands.
Not every cabinet has the same locking requirements. The JK312 allows the key to turn the lock cylinder at either 90 degrees or 180 degrees, giving you the freedom to choose the rotation that best fits your design. In addition, the functional body length of the lock, which is the distance from the mounting surface to the cam, is available in multiple standard sizes. This ensures easy installation on doors and panels of different thicknesses, saving you time and reducing the need for custom modifications.
The cam or latch is a key part of any cam lock. The JK312 supports a wide variety of cam shapes and sizes, so you can select the ideal configuration for your specific enclosure. Whether you need a straight cam, an offset cam, or a specially shaped latch, we have standard options ready. Moreover, we welcome custom orders for cams based on your drawings or samples. This high level of customization means the JK312 can be adapted to secure almost any type of swing handle, strike, or locking point.
Because of its robust design and versatile features, the JK312 is already used in many demanding applications. Common examples include arcade gaming machines, where secure coin box access is essential, and ATMs or financial kiosks that require highsecurity locking. It is also widely found in electrical distribution cabinets, protecting sensitive components from unauthorized entry, as well as in EV charging station enclosures, where weather resistance and tamper protection are critical. In addition, floor standing advertising displays, often called digital signage cabinets, rely on the JK312 to prevent vandalism and theft of internal media players.
The JK312 cam lock combines industrial grade materials, multiple functional lengths, selectable rotation angles, and interchangeable cams, all backed by our strict quality control. It has become our top seller because it solves real problems for real customers, and it continues to be the first choice for engineers and purchasers around the world. Whether you need a standard off the shelf solution or a fully customized lock, our team is ready to support you.
