4900 Heavy
Duty Deadlatch

ALUMINUM

4900 Heavy Duty Deadlatch provides flexible traffic control
and easy installation.

Function

Flexibility of traffic control and installation is offered by 4900 Heavy Duty
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 and 4700 Deadlatch
preparations. 1-3/4" minimum door thickness required.

Operation

Turn key or operate handle or paddle to retract spring-loaded Latchbolt. To hold
bolt retracted, push it in and secure by reverse turn of key. Uses any standard
1-5/32" mortise cylinder with MS® dimensioned cam.

• While bolt is held fully retracted, a

reverse turn of the key retains the bolt,
allowing the door to be free swinging.

CASE

• Measures 7/8" x 5-13/16" x depth. Depth varies by backset

(see table on back of page). Steel with corrosion-resistant
plating. Screw-fastened tube spacer brackets allow for
cleaner removal when tab mounting.

LATCHBOLT

• 5/8" x 1" x 5/8" throw. Solid brass. Handing is easily

reversible using only a screwdriver.

AUXILIARY LATCHPIN

• Stainless steel. Deadlocks Latchbolt to prevent “loiding”

• Measures 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.

door closes flush or nearly flush. Specify 4901 for retrofit
installations. Also available: radius strike for opposite stile in
