Your Current Selections:
  • 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.
Adams Rite 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.

Case Size: 7/8 (W) x 5 13/16 (H) in., Face Plate Size: 1.00 (W) x 6.88 (H) in.


1 1/2 in., 1 1/8 in., 31/32 in.

    It’s been a few months now and my new lock system is working great! Thanks GoKeyless for the outstanding lock. The quality is great and the customer service was even better. I look forward to new business in the future. My door is sucre and the customer loves the keyless entry to the store. Perfect fit for my Postal Center. BOX IT PLUS

    I have spec’ed and used Adams Rite hardware for many years. It has excellent life and always works. The 4900 I purchased has flexibility of adding keyless pad in the future which I may do. Adams Rite is just good hardware and GoKeyless always has competitive pricing and quick delivery.
