3140 - AUTOMATIC FLUSH BOLTS - SINGLE TOP BOLT

3 Hour UL-Rated Fully Automatic Single Top Flush Bolt for up to 8' x 9' Metal Doors

Flush bolts by Hiawatha are UL-Listed and are installed in the top and bottom of the inactive door.  Closing the inactive door automatically extends both top and bottom bolts 3/4" into frame and sill strikes, locking inactive door.  Opening the active door retracts top and bottom bolts, releasing the inactive door. 
Non-handed flush bolts with patented free floating cams require a maximum of 5 lbs force on active door. Bolts can be vertically adjusted up to 1-1/2". Requires 2" clearance.  When ordered with bottom fire bolt BFBM, eliminates the need for bottom automatic flush bolt and dust proof strike.
