Vibration-Resistant Grab Latches with Electrical Switch
![](/prerenderstable/mvPRE/contents/gfx/imagecache/128/12855a61c1-h02d-digital-master1580487240-p9@halfx_637160624540690034.png?ver=imagenotfound)
An electrical switch allows these latches to power a light or other signal to indicate whether a door is open or closed. Their spring-loaded design withstands vibration, rattling, and shaking better than other push-to-close grab latches for a more secure hold. Latches meet UL 94 V-0 for flammability. Note: These latches are not for use as access safety switches.

A red indicator on the lock face is visible when unlocked and hidden when locked. Also known as a compression cam lock, turn the head a quarter-turn to latch, then another quarter-turn to draw the cam firmly against the door or drawer surface. This lock is IP65 and NEMA 4 rated for protection against dust, dirt, and washdowns. It comes with a straight cam and two reversible offset cams to accommodate different latching distances.

Tight-Hold Square-Drive Cam Locks for Pressurized Enclosures
![](/prerenderstable/mvPRE/contents/gfx/imagecache/499/4996n11-@halfx_mecwj_1718993791.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 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.

Open-Indicating Tight-Hold Hex-Drive Cam Locks
Spot when these locks are open with just a glance—a red indicator shows they're unlocked. Also known as compression cam locks, their cam seals more tightly against a door or drawer than a standard cam to reduce rattling from vibration. Using a hex key, turn the head a quarter-turn to lock, then another quarter-turn to draw the cam firmly against your surface. Since they lock with a hex key, they’re great if you want a simple keying system. All come with multiple cams to accommodate different latching distances.
To help maintain a sealed enclosure's IP and NEMA rating, these locks have a gasket that stops water and dust from getting past the lock. Made of stainless steel, these locks resist corrosion, even in environments with constant moisture.
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 when precise latching 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.

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.

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.

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. Turn the head a quarter turn to lock, then turn it another quarter turn to create compression. The second turn also reduces rattling from vibration. A gasket or an O-ring helps keep low-pressure washdowns and dust from entering through the lock. This helps you maintain your sealed enclosure's IP or NEMA rating. All of these locks open with a slotted screwdriver, so they’re good for areas where you don’t want a complicated keying system.
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. Those with straight and offset cams include multiple cams, so you can change the fixed latching distance.
Locks with an adjustable latching distance handle a wide range of latching distances, so they’re best for tasks when 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.
Aluminum locks stand up to corrosion better than zinc locks. They are also lighter in weight than zinc and stainless steel locks.
Use stainless steel locks in areas that are constantly exposed to moisture since they resist corrosion better than zinc and aluminum locks.
