Krieger Cam Lift Hinges
Designed for Lasting Performance and Easy Maintenance
Now Comes in Standard and Electrified Options
Krieger's HC30 Cam Lift Hinge is an industry game-changer featuring a new design that enhances radial strength to support heavy loading and ensure longer lasting performance. Easy to maintain, the Cam Lift Hinge comes with an optional security pin and is fully ADA compliant.
Easy, Time-Saving Maintenance
A new fitting at the bottom of the Cam Lift Hinge makes it easy to keep lubricated—without having to remove the door from its hinges.
Now one person can do in a matter of minutes what used to take two or more people hours. Keeping hinges properly lubricated and maintained improves performance and extends the lifeof the door.

100% ADA Compliant
Krieger’s lab testing of the Cam Lift Hinge shows it to be fully compliant with the Americans with Disabilities Act (ADA) requirements regarding the maximum force required to pull the door open—less than 5 pounds on door leaves under 500 pounds.
The versatility of the Cam Lift Hinge means it can be used in any location, even for heavy doors.

Security Pin Upgrade
For applications that require pressure and forced entry resistance, our Cam Lift Hinges can be upgraded with a security pin. This feature works by preventing the door from opening in the event of an attempted forced entry, causing a time delay and adding an extra level of security.
The security pin can also be used in place of a continuous hinge to maintain the blast rating for blast-resistant doors. Contact us for more information.

Designed for Radial Strength
Our Cam Lift Hinges feature a proprietary design that reinforces the hinge from top to bottom without the use of a Teflon™ sleeve, which had been prone to wearing out.
This solution allows the hinge to support heavy loading and, along with the stainless steel, offers superior strength and long-term durability.

Tight Acoustical Seal
The Cam Lift Hinge enables the door bottom seal to be adjusted quickly and accurately at the time of installation and also for adjustment after many years of operation.
Additionally, our Cam Lift Hinges accommodate for a 13mm total vertical rise to ensure that the door easily clears any floor coverings after it swings past the threshold. When closed, the Cam Lift Hinge lowers into place for a tight seal.
