Product Description
Mortise exit devices latch through a mortise lock case set into the edge of the door — the same pocket a mortise lockset uses. The door must be prepped for the mortise case before you order.
The Sargent 125556-8974J-LHR-3 is a fire-rated Grade 1 mortise exit device from the Sargent 80 Series (8900 mortise) for 42" openings with Fail Secure function. UL listed for fire-rated openings up to 3 hours.

This device is Left Hand Reverse. Exit devices are HANDED and cannot be reversed in the field. Stand outside the door facing it: hinges on the left = Left Hand, hinges on the right = Right Hand. If the door swings toward you, add "Reverse." Verify your handing before ordering.
Fire Rated (12- prefix) — This device is UL listed for fire-rated openings. Do NOT substitute a non-fire-rated device (8- prefix) on a fire-rated opening — your fire marshal will require removal and replacement.
Bright Brass — the classic 03 finish. Traditional, formal, and still specified on government buildings, courthouses, and historic renovations.
Pro-Tip from Our Locksmiths: Fire-rated exit devices (12- prefix) are NOT interchangeable with non-fire-rated (8- prefix). Your fire marshal will make you rip out a non-fire-rated device installed on a fire-rated opening. Always check the door label first.
