Overview
About this product
The ND78 classroom security lock with the Rhodes lever has a key cylinder on both sides, so a teacher can lock the outside lever from inside the room. This 180 degree lockdown version is suited to classrooms and other rooms where occupants may need to lock the door from inside.
The Rhodes lever sits on a 3-7/16 in. Rhodes rose over a deadlatch with a 1/2 in. throw. The lock is ANSI/BHMA A156.2 Series 4000 Grade 1 as ANSI function F110, UL listed for 3-hour fire doors, and fits 1-5/8 to 2-1/8 in. doors at a 2-3/4 in. backset.
What the function does
There is a key cylinder on each side of the door. A key from inside the room locks the outside lever, so the door can be secured without opening it or stepping into the hallway. The inside lever always lets people leave.
