Leading Cam Lock Manufacturers

Cam locks are L-shaped locking mechanisms used to secure lockers, cabinets, and other enclosures. They are made up of a tongue bar and a cylindrical keyed nut as their major components. After installation, you can lock the enclosure by twisting the former section while inserting a key. Read More…

Cam Locks A cam lock is a kind of latch or fastener that is meant to affix two or more parts together. It consists of a base and a cam, in which a key is inserted into the base to rotate the cam, anywhere from 90 to 180 degrees, thus latching and unlatching the lock.

Cam Locks

How Cam Locks Function

Cam locks come in various varieties, but they all function similarly. Directly within the front of an enclosure are positioned cam locks. When installed, the front of the cam lock must remain flush with the front of the enclosure.

Cam locks need to be locked and unlocked with a key. The position of the tongue bar will change when a key is inserted into a cam lock and turned. The tongue bar will move in one of two directions when the key is turned- sideways or vertically. The tongue bar will lock the enclosure when tipped to one side. Conversely, when the tongue bar is vertical.

How Cam Locks are Made

Volker Guelck, a Canadian inventor, came up with the cam lock in 1985. For cabinet drawers, safety boxes, lockers, doors, windows, and many more compartments, cam locks serve as quick and simple security systems. Rather than oscillating like a piston, a cam lock is a form of a latch with a bolt, sometimes known as a "cam," that spins around a rotation axis going through one end of the cam. Usually, a rotating plug, like a screw, is directly attached to a cam through the rotation axis. A cam lock can also be adjusted by turning a lever to pinch a door, window, or cabinet panel to its frame.

What to Consider When Selecting Cam Locks

Different materials are used to make various cam locks. A common material used to create cam locks is zinc alloy. Any metallic substance that contains zinc and at least one other metal is known as a "zinc alloy." For instance, brass, a zinc alloy, is frequently utilized in manufacturing cam locks. Consider having them keyed alike if you intend to purchase several cam locks. "Keyed alike" refers to cam locks that all operate with the same key. You won't need to manage numerous keys, whether you get six cam locks or one hundred. All cam locks can be locked and unlocked with the same key.

Cam Lock Applications

Every industry typically uses cam locks, including manufacturing, agricultural, oil, gas, chemical, pharmaceuticals, and military applications. This pairing is incredibly adaptable. Since it doesn't use threads, there are no concerns about it getting soiled or breaking. Cam lock couplings are ideal for soiled situations as a result. In addition, these couplings are ideally suited for applications where regular hose replacements are necessary, such as industrial chemical and petroleum vehicles, used on tanks that contain liquids and powders, as well as with pumps, hoses, tubing, and tanks.

Used in practically every industry where the transportation of liquids and powders is necessary, including those that deal with fuel and oil, water, chemicals, paints and dyes, food and beverage, adhesives, pharmaceuticals, cleaning supplies, and agriculture.

Materials to Consider When Choosing a Cam Lock

Stainless Steel

In extremely corrosive environments, stainless steel is the best material to use. An inner wall of a stainless steel cam lock coupling will be clean, preventing impurities, condensation, bacterial growth, the formation of strange smells, and media pollution. Stainless steel has excellent temperature resistance; it can operate safely between extreme temperatures (-30°C and 230°C) for an extended time. For specialized jobs where pipes may move or require more strength, it's a stronger, more resilient solution. It naturally resists corrosion and requires little upkeep.


For water or waste in corrosive situations like those near salt water in the ocean or where the couplings must be non-sparking, like in marine fuel applications, choose bronze cam locks, one of the oldest alloys. Additionally, it can be employed in shipbuilding and deep-well operations.


Utilize aluminum cam locks in low-demand fluids, including fresh water and oil-water mixtures. It has good plasticity and can be treated in a variety of profiles. It is also a superior thermal and electrical conductor. It is typically less expensive and resistant to corrosion.

Types of Cam Locks

  • Type A – male adaptor with female NPT thread
  • Type B – female cam coupler with male NPT thread
  • Type C – female cam coupling with hose barb end
  • Type D – female cam coupler with FNPT thread
  • Type E – cam adaptor with hose barb end
  • Type F – cam lock adaptor with male NPT thread
  • Type DC – dust caps for male adaptors
  • Type DP – dust plugs for female couplers
Cam Lock Couplings
  • Safety Locks for Cam Lock Couplings: Using safety locks will prevent accidental opening of cam lock arms. They are an affordable alternative to more expensive locking handles, and they are also simple to set up and take down.
  • Cam Lock Coupling Chains: These chains can join a type B, C, or D coupling or plug with a type DP dust plug or DC-type dust cap.

Safety & Preventative Maintenance for Cam Locks

A regular maintenance program that enables you to check your cam lock couplings frequently is recommended. As moving elements of cam lock couplings are prone to wear and tear, inspecting and replacing worn pieces frequently is crucial. You may increase your products’ lifespan and ensure that health and safety requirements are satisfied by replacing old parts.

Choosing the Proper Cam Lock Manufacturer

To make sure you have the most productive outcome when purchasing cam locks from cam lock manufacturers, it is important to compare at least five manufacturers using our list of cam lock manufacturers. Each cam lock manufacturer has a business profile page that highlights their areas of experience and capabilities and a contact form to directly communicate with the manufacturer for more information or request a quote. Review each cam lock company website using our patented website previewer to get an idea of what each business specializes in, and then use our simple RFQ form to contact multiple cam lock manufacturers with the same message.
