Spec Sheet

MS1880 and MS1881 Two-Point Flushbolts offer greater
convenience than flip-lever flushbolts. With one operation,
they provide security and reduce human error.
MS1880, MS1881
Two-Point Flushbolts
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.
Operation
Turn knob or lever 180° clockwise to throw hardened steel bolts
into header and threshold and clear strike opening so pivoted
MS® bolt can enter from active door. Counterclockwise turn
retracts vertical bolts and blocks entry of pivoted bolt.
Operates in conjunction with any MS
®
pivoting deadlock.
