4781 Two-Point
Deadlatch with Paddle

ALUMINUM

4781 TWO -POINT DEADLATCH WITH PADDLE

Inside Operation

Push paddle to unblock top bolt and withdraw bottom bolt.
Continuing to push will open the door in a very natural,
ergonomically-friendly motion. Paddle stroke is approximately
1-1/2" at extreme end. Rod adjustment allows paddle
(centerline) to be mounted at any height from 30 to 44 inches
above the finished floor.

Outside Operation

If key entry operation is required, any standard mortise cylinder
with MS® cam can be installed through an 8650 Cylinder
Escutcheon. Any of the entry trim available with Adams Rite exit
devices can be specified, in the version used for CVR devices.

DA-7

The 4781 Two-Point Deadlatch latches to header and
threshold allowing both door leaves to remain active. It is
designed for paired outswinging narrow stile doors, but is
also suitable for single doors.

Function

Designed for paired outswinging narrow stile doors but also suitable for single
doors. Instead of operating a conventional horizontal-throw latchbolt, the 4781
Two-Point Deadlatch latches to header and threshold. This allows both door
leaves to be “active”. There is no need to pin one door with flushbolts or other
devices. The paddle is a modified version of the 4591 Deadlatch Paddle (see
TRIM) and the concealed vertical rod mechanism is the same as used in Adams
Rite’s 8600 Series Exit Devices (see EXIT DEVICES). Note, however, that the
4781 Two-Point Deadlatch is not intended to substitute for an exit device, which
must have a door-spanning bar.

Specifications

PADDLE DOGGING

• Turning hex screw in paddle escutcheon holds paddle

down, leaving door free-swinging.

TOP BOLT

• Similar to door latches on some automobiles and aircraft,

the U-shaped bolt wraps around the strike post to
deadlock position, which also deadlocks the bottom bolt
through a gear train at the center of the rod assembly.

HEADER STRIKE

• A flanged post installed on the header has generous

location adjustment to allow for door misalignment,
sag, bumpers, etc. Designed to prevent forced entry
by bowing the door.

BOTTOM BOLT

• Stainless hexagonal steel bolt requires only a 1/2"

diameter hole in threshold for a strike.

DOOR SIZE

• Standard unit will fit doors up to 66" above the paddle

height (110" door if paddle is at max 44" height).
For taller doors, order 8655 Tall Door Kit, which allows up
to 97" above paddle.

OPTIONS

• Can be exit only or allow key access from outside

with use of 8650 Cylinder Escutcheon. Entry trim
available with Adams Rite exit devices can also be
specified, in the version used for CVR devices.

STA NDARD PACKAGE

• Individually boxed with mounting screws and installation

instructions. Shipping weight: 3 lbs.
