Lockey's Heavy Duty Panic Bar Lock!
If you are looking for a high-quality, heavy-duty keyless combination lock with a built-in lever handle that will work with a panic bar, take a look at this lock.
The 1150P Panic Bar lock works with a standard horizontal style panic bar on doors that are either right handed or left handed. The panic bar must have a flat tail piece and a 70 degrees turn radius or less.
The 1150P has a built-in, easy-to-operate lever handle on the outside which is ADA-compliant if mounted no more than 48 inches from the floor.
This lock also has a passage mode so you can come and go without using the combination, if you prefer. This makes it ideal for an office environment where the door should remain unlocked during business hours, but locked after hours. You will need to know the code, of course, to enable the passage mode.
