IVES FLUSH BOLTS OVERVIEW

Ives offers many accessories to ensure that a door is hung, protected and secured. Flush bolts can be used on doors that need to be secured without having a mullion or wall for latching. Flush bolts are usually used on a pair of double doors, like a large closet in a commercial building or French doors.These doors may have a lock, but the flush bolts allow one door to be anchored to the top of the door and the floor. The other door can then latch to the anchored door and keep the opening secure when not in use.

There are many types of flush bolts to accommodate various doors types, sizes and application needs while also matching existing or new door hardware. Flush bolts are recessed into the top and bottom of the door edge and slide upward or downward into the jamb or threshold to keep the door secure and closed.

DESIGNS & FINISHES

Designs

Flush bolts provide a secure opening by latching the inactive door. Designs include the offerings below. For more specific models within each offering, see the Ives Full Line catalog.

• Automatic flush bolt: Fully automatic flush bolts ensure the inactive door is latched and bolts are extended when the active door closes. The inactive door is unlatched and the bolts retract when the active door is opened.
• Constant latching flush bolt: Constant latching flush bolts ensure the inactive door remains latched until the active door is opened, releasing the automatic bottom bolt and then the top bolt can be manually released. The inactive door will re-latch automatically when the door closes.
• Manual flush bolt: Manual flush bolts must be extended and retracted manually, depending on when the inactive leaf needs to be secured or opened.
