Function:
Used instead of flip-lever flush bolts in the inactive leaf of paired doors, the MS1880 Two-Point Flushbolts offer greater convenience: one operation instead of two. They also promote security by removing an element of human error. A positive locking device makes it impossible to turn the key in the active door unless the inactive leaf has first been secured.

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 the active door. Counterclockwise turn retracts vertical bolts and blocks entry of pivoted bolt. Operates in conjunction with any MS pivoting deadlock.
