QEL (Quiet Electric Latch Retraction) is a feature available on exit devices that provides electronic control of the latch with minimal operational noise. QEL-enabled exit devices are ideal for environments where quiet operation is important, such as hospitals, libraries, offices, or residential settings.

SECLOCK carries QEL exit devices from brands like Von Duprin, SARGENT, and others.

Key prep refers to the cylinder/keyway configuration for locks.
