Miniature Tight-Hold Square-Drive Cam Locks
![](/prerenderstable/mvPRE/contents/gfx/imagecache/502/5028n11-@halfx_d9w1i_1718048499.png?ver=imagenotfound)
Prevent cabinet doors, drawers, and other enclosures with smaller-than-standard diameter through holes from vibrating open. Also known as compression cam locks, these locks create a tighter hold than standard cam locks, making them useful for doors that have a seal. Turn the head a quarter turn to lock, then turn it another quarter turn to create compression. The second turn reduces rattling from vibration. A gasket prevents water, dust, and dirt from getting into an enclosure through the lock. This helps you maintain an IP65 rating in your sealed enclosure.
These locks open with a square key (sold separately), so they're more secure than locks that open with a hex or slotted driver yet still match a common keying system for industrial enclosures and other machinery. Their concealed design also stops others from tampering with them using pliers. These locks have an adjustable latching distance and multiple cams to adapt to a wider range of distances than other locks with a fixed latching distance. They’re best when precise distances are unknown.

Tight-Hold Square-Drive Cam Locks for Pressurized Enclosures

Mount these two-piece locks on sealed pressurized enclosures to gradually release pressure and prevent your door from bursting open. A quarter turn partially opens the door and lets the pressure escape while the door is still latched. Another quarter turn fully opens the door. Also known as compression cam locks, these locks create a tighter hold than a traditional cam lock, making them useful for doors that have a seal. To lock, turn the head a quarter turn, then another quarter turn to create compression and minimize rattling from vibration.
These locks open with a square key (sold separately), so they're more secure than locks that open with a hex or slotted driver yet still match a common keying system for industrial enclosures and other machinery. They have a concealed design to stop others from tampering with them using pliers. Since these locks do not extend inside the enclosure when installed, you’ll have full use of the inside space.

A spring-loaded bushing keeps your enclosure door from vibrating open. These locks combine the vibration resistance of a tight-hold lock with the simple operation of a quarter-turn cam lock. However, they don't close as tightly as tight-hold locks. All have an arm that rotates 90° to secure your enclosure. They include multiple cams, so you can change their fixed latching distance. Since you won’t have to adjust the cams into position, these locks are faster to install than those with an adjustable latching distance.
These locks open with a square key (sold separately), so they're more secure than locks that open with a hex or slotted driver yet still match a common keying system for industrial enclosures and other machinery. They have a concealed design to stop others from tampering with them using pliers. An O-ring or gasket helps keep dust and low-pressure washdowns from entering through the lock. This helps maintain your sealed enclosure's IP or NEMA rating.
Use stainless steel locks in areas that are constantly exposed to moisture since they resist corrosion better than zinc locks.
Style A locks have a flat surface that offers more security and dust protection than typical cam locks. Their bushing remains depressed when the lock is not fully closed, so you can see when the latch is not secure.

Miniature Square-Drive Cam Locks
Secure enclosures that have smaller-than-standard-diameter through holes. These locks open with a square key (sold separately), so they’re more protected than locks that open with a hex or slotted driver. They match a keying system that is common for industrial enclosures, control cabinets, and other machinery, so you can keep a simple keying system around your facility. Their concealed design stops others from tampering with them using pliers. Also known as quarter-turn locks, these locks have an attached arm that rotates 90° to lock your enclosure. A gasket prevents water, dust, and dirt from getting into an enclosure through the lock. This helps you maintain an IP65 and NEMA 4 rating in your sealed enclosure. All come with multiple cams to accommodate different latching distances.
Pull tabs (sold separately) make opening your door or panel easier.
Sealing covers (sold separately) keep water and dust from getting inside the lock cylinder.
