Environmental Performance:
The lock may be used in both indoor and outdoor applications. Outdoor applications require use of a PowerLever Pro-Gasket™ Kit for maximum performance.
Note: For outdoor applications where the lock is unprotected from freezing rain or rain followed by freezing temperatures, a Pro-Guard™ Weather shield must be installed over the lock to prevent ice from forming between the keybuttons and the outside cover.
The lock will perform satisfactorily in the following environmental conditions:
