MS1880

Top and Bottom Bolts

Hexagonal 3/8“ flat to flat. Stainless steel. Guides furnished. Bolt ”throw” is .72 inch. Strike required in metal headers and thresholds is 1/2” diameter hole. For wood installation order two 4005 strikes separately.

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. Operated in conjunction with any pivoted bolt MS deadbolt. Cannot be unlocked when pivoted bolt is in locked position. Not to

be used as a stand-alone locking mechanism.

MS1881

Turn/Indicator

Operates in conjunction with any MS

pivoting

Deadbolt

MS1880 has hourglass shape for firm finger grip. Finish is US26D Satin Chrome (682). Red background indicator has aluminum letters reading “LOCKED”. (No message shown when unlocked.) MS1881 has teardrop shape lever with red letters on clear decal indicating unlock direction only.

Interlock

All steel mechanism includes device to prevent entry of pivoted bolt until vertical bolts are locked and to prevent unlocking of vertical bolts when pivoted bolt is locked.

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.
