Adams Rite Flushlock MS1880 Series MS®, Two Point Flushlock, For Aluminum Swinging Doors

Adams Rite flushbolt door locks provide greater key control and are designed to prevent accidental locking of the inactive leaf of paired doors. This two point flushlock provides maximum security for aluminum swinging doors.

Strike: Strike required in metal headers and thresholds is 1/2" (12.7 mm) diameter hole.

For wood installation, two 4005 strikes are required, available separately.

Turn Shape: This flushlock comes in a choice of two turn shapes:

• MS1880: Hourglass shaped turn for firmer finger grip.

Red background indicator has aluminum letters reading “LOCKED” when secure.

• MS1881: Teardrop shaped turn. 

Red letters on clear decal indicating unlock direction only.

Turn Height: Matches cylinder height of MS® lock in active door.

Cylinder Height: Distance from the floor to the center of the cylinder hole.

This flushlock comes in a choice of cylinder heights:

• 31" to 35" 
• 35-1/16" to 39" 
• 39-1/16" to 43"
• 43-1/16" to 47"
• 47-1/16" to 51" 

Installation: The MS1880 cannot be used as a standalone locking mechanism and must be installed in conjunction with a pivoting MS® Deadlock, sold separately. For details on how to install this flushlock, see our Installation Instructions.

Operation: 180° clockwise turn of the knob or lever hardens the steel bolts into the header and threshold and clears the strike opening so the pivoted MS® bolt can enter from the active door. Counterclockwise turn retracts the vertical bolts and blocks entry of the pivoted bolt. Operates in conjunction with any pivoting MS® Deadlock, sold separately. A positive blocking device makes it impossible to turn the key in the active door unless the inactive leaf has first been secured. Cannot be unlocked when pivoted bolt is in a locked position.

Additional Options: Tall door kit for doors over 84" (2,134 mm) is available, please contact us for details and pricing.
