The MS1880-05-121 from Adams Rite is a two-point flushbolt with an hourglass shaped turn in dark bronze anodized. The MS1880 Series Two-Point Flushbolts offer greater convenience than flip-lever flushbolts as it is processed with 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. It Cannot be unlocked when the pivoted bolt is in the locked position. For its operation, turn the knob or lever 180 degrees clockwise to throw hardened steel bolts into the header and threshold and clear the strike opening so the pivoted MS bolt can enter from the active door. Its counterclockwise turn retracts vertical bolts and blocks entry of the pivoted bolt.
