Adams Rite 4900

• Uses any standard 1-5/32" mortise cylinder with MS cam
• Includes bolt-holdback feature: a reverse turn of the key (while using finger to press in the latchbolt) allows the door to be free-swinging. This enables two-way traffic at hospitals, banks, stores, and other buildings that are required to have an unimpeded free entrance at certain times and exit-only at other times.
• Backset Size: Choose from 1 1/8" and 1 1/2" - How do I measure?
• Handing: Choose right or left. If you get it wrong its no problem, you can reverse handing in the field with a screwdriver. It's easy.

Hailed as Adams Rite's top-of-the-line deadlatch.  (no plastic parts, easiest to reverse handing in the field).  Designed to interface with your new narrow-stile keyless entry and narrow stile door.  With a rich heritage in quality, Adams Rite locking devices can be found on nearly all of today's commercial glass doors with 1 3/4" aluminum stiles.   The 4900 is the deadlatch only.  It will match up to the Adams Rite exit paddle, and Adams Rite deadlatch handle.  If you do not currently have a paddle or lever, be sure to order one.  Your keyless lock, this deadlatch, and the interior paddle (or lever) are the three necessary components to complete your access control system.Adams Rite exit paddle, and Adams Rite deadlatch handle.
