Syntegra
LX Series
Lever Operated Openings
The LX Series exemplifies Syntégra’s “deeper integration” attitudes and goals. The central lock case accepts handles and keyed cylinders from either and/or both sides. The lock case is configurable with the same popular functions offered in conventional locksets, but we can also do much more. The lever handles are protected by a break-away clutch allowing these systems to be used in the most abusive and demanding applications. Syntégra door systems do not use bulky escutcheons, roses, or edge plates to hide door preparations and mechanisms. Only the vital elements that are needed for operation are exposed, and everything else is concealed and protected.
Imagine being able to operate and secure each leaf of a pair of doors independently without the need for coordinators, astragals, and manual flushbolts. Pairs and single doors also benefit in concealing the side latch and strike from view and tampering by latching at the top of the door. With electrical functions such as electrified lever (ELS) and electrified latch retraction (ML), the LX Series will interface with virtually any access control and door automation system.

Customer-Favourite Commercial Rollup Doors
Depending on your needs, we have an extensive selection of high-performance, energy-efficient and fire-rated products to choose from, including the following.

- EntryDefender™ High-Security Door: The EntryDefender™ Door meets the U.S. Department of State Standard for forced entry for a five-, 15- and 60-minute mob-style attack.
FIRE-RATED ROLLUP SERVICE DOORS
Rollup fire doors are rated structural fire barriers that help block the spreading of hazardous fire and smoke by compartmentalizing a building space and keeping the event isolated. Many buildings today mandate the placement of rolling steel fire doors as a standard safety precaution.
The Firemiser Insulated Rolling Fire Door is perfect for an exterior application and reduces sound transfer thanks to mineral wool insulation. Mineral wool insulation also minimizes thermal transfer, which can help you with temperature control inside your building. Opt for the SmokeShield™ seal package for your fire-rated door if you’re required to conform to UL 1784 or want an additional barrier to eliminate smoke migration throughout your building.
