Adams Rite 4900 HD Deadlatch, Aluminum Stile Doors
More Info +
The heavy duty 4900 Deadlatch for aluminum stile doors features 5/8" solid brass latchbolt that is reversible by simply removing a screw with a standard screwdriver. Normally fitted with cylinder outside and lever or paddle inside to allow traffic control. The latch can also be held retracted for unrestricted access.
Steel with corrosion-resistant plating. 7/8 x 5-13/16 x depth. (Depth varies by backset. See table on back page.) Screw-fastenend tube spacer brackets allow for cleaner removal when tab mounting.
Flexibility of traffic control and installation is offered by the 4900 Series Deadlatches. A reverse turn of the key while bolt is held retracted retains the bolt, to allow two-way traffic for applications which require free entrance at certain times and exit-only at other times. Interchangeable, without stile modification, with any MS1850A or MS1850S deadbolt of same backset and faceplate shape. Also retrofits to existing 4500/4700 Deadlatch preparations. 1-3/4" minimum door thickness required.
5/8 x 1 x 5/8 throw. Solid brass. Handing is easily reversible using only a screwdriver.
Stainless Steel. Deadlocks latch bolt to prevent “loiding” or case-knife entry.
1 x 6-7/8 . Both flat and radius faceplates are supplied. Flat faceplates can also be adjusted in the field for right or left beveled edge doors.
Turn key or operate handle or paddle to retract springloaded latch bolt. To hold bolt retracted, push it in and secure by reverse turn of key (see back page). Uses any standard mortise cylinder with MS® cam.
