ALUMINUM
MS1880 and MS1881 Two-Point Flushbolts offer greater
convenience than flip-lever flushbolts. With one operation,
they provide security and reduce human error.
Function
Used instead of flip-lever flushbolts in the inactive leaf of paired doors, the
MS1880 and MS1881 offer greater convenience: one operation instead of two.
It also promotes security by removing an element of human error. A positive
blocking device makes it impossible to turn the key in the active door unless the
inactive leaf has first been secured. This two-point flushbolt must be installed in
conjunction with a pivoted bolt MS® deadlock. Cannot be unlocked whe pivoted
bolt is in locked position. Not to be used as a standalone locking mechanism.
TURN/INDICATOR
• MS1880 has an hourglass shape for firmer finger grip.
Finish is US26D Satin Chrome (682). Red background
indicator has aluminum letters reading “LOCKED˝
(no message shown when unlocked). MS1881 has a
teardrop shape lever with red letters on clear decal
indicating unlock direction only.
TOP AND BOTTOM BOLTS
• Hexagonal 3/8" flat to flat. Stainless steel. Guides
furnished. Bolt throw is 23/32". Strike required in metal
headers and thresholds is 1/2" diameter hole. For wood
installation, two 4005 strikes required are available
separately.
INTERLOCK
• All steel mechanism includes device to prevent entry of
pivoted bolt until vertical bolts are locked and conversely, to
prevent unlocking of vertical bolts when pivoted bolt is locked.
