PRICED PER PIECE
This two point deadlatch is for narrow stile aluminum swinging doors.
Please note: Strike, cylinder and/or thumbturn are not included with this product and are available for purchase separately.
Vertical Rod: Concealed vertical rod mechanism is the same as in the 8600 Series Exit Devices. However, the 4781 Deadlatch is not intended to be substituted for an exit device, which must have a door-spanning bar.
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.
Threshold Bolt: Stainless hexagonal steel bolt requires only a 1/2" (12.7 mm) diameter hole in the threshold for a strike.
Paddle:Â Paddle is a modified version of the 4591 Deadlatch Paddle.
Paddle stroke is approximately 1-1/2" (38.1 mm) at extreme end. Rod adjustment allows paddle (centerline) to be mounted at any height from 30"-44" above the finished floor.
To allow the door to be free swinging, turn the hex screw in the paddle escutcheon to hold the paddle down.
Door Type: For narrow stile aluminum swinging doors. Designed for paired out swinging doors, but also suitable for single doors.Â
Standard unit will fit doors up to 66" (1,676.4mm) above the paddle height. Please contact us for an allowance of up to 97" above the paddle for taller doors.
Installation: For details on how to install this deadlatch, see our Installation Instructions.
Operation:Â
- Inside: Push the paddle to unblock the top bolt and withdraw the bottom bolt. Continuing to push will open the door in a very natural, ergonomically-friendly motion.Â
- Outside: If key entry operation is required, any standard mortise cylinder with MS® cam can be installed.
Compatible Cylinders:
- Adams Rite #4036 - Mortise Cylinder
- Adams Rite #4066 - Thumbturn Insert
