Also known as compression cam locks, turn the head a quarter-turn to latch, then another quarter-turn to draw the cam firmly against the door or drawer surface. These locks are IP65 and NEMA 4 rated for protection against dust, dirt, and washdowns. Each lock comes with a straight cam and two reversible offset cams to accommodate different latching distances.

Open-Indicating Tight-Hold Triangle-Drive Cam Locks
The spring-loaded cover pops up when these locks are open, so you’re able to see from a distance when they're unlocked. When shut, the cover keeps water and dirt from getting inside the lock cylinder to prevent damage. Also known as compression cam locks, they create a tighter hold than standard cam locks in high-vibration environments. Turn the head a quarter-turn to latch, then another quarter-turn to draw the cam firmly against the door. The second turn creates compression, which is ideal for enclosures with a seal and reduces rattling from vibration. They open with a triangle key (sold separately), so they match a keying system that's common for industrial enclosures and other machinery but are more secure than locks that open with a hex or slotted driver. Their concealed design stops others from tampering with them using pliers.
Locks with a fixed latching distance are best when you know the precise distance you need. Since you won’t have to adjust the cam into position, these are faster to install than those with an adjustable latching distance.
Locks with an adjustable latching distance are best for installations where precise distances are unknown. Adjust the position of the cam before you begin to install them. They project further into the enclosure than those with a fixed distance.
Stainless steel locks resist corrosion when exposed to constant moisture.
When installed in a sealed enclosure, these locks help maintain your enclosure's IP or NEMA rating. They all seal out dust and dirt but have various levels of water protection. IP65 locks help seal out water from low-pressure washdowns. IP67 locks help seal out water from temporary submersion. NEMA 4 locks help seal out water from washdowns and the weather.

Miniature Triangle-Drive Cam Locks
Designed for smaller-than-standard-diameter through holes, these locks are often installed in cabinet doors. They open with a triangle key (sold separately), so they’re more secure 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.

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 triangle 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 helps keep dust and low-pressure washdowns from entering through the lock. This helps maintain your sealed enclosure's IP65 rating.
Use stainless steel locks in areas that are constantly exposed to moisture since they resist corrosion better than zinc locks.
Style B 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.

Tight-Hold Triangle-Drive Cam Locks for Pressurized Enclosures
![](/prerenderstable/mvPRE/contents/gfx/imagecache/492/4922n11-@halfx_1srxn_1719322252.png?ver=imagenotfound)
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 triangle 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.
