The standard rods that are supplied with the FB30 and FB50 Series Flush Bolts cannot be cut in the field because they are not threaded the entire length
Ives offers replacement rods that can be used on the FB31T and FB51T Top Flush Bolt for a 9", 18", 24", 30", 36" or 48" dimension from the top of the door to the Centerline of the Top Flush Bolt faceplate.
These replacement rods are threaded all the way so they can be cut in the field if desired but should not be used on the FB31B or FB51B Bottom Flush Bolts.
The standard (12" dimension) rod supplied with the FB30 and FB50 Series Flush Bolts must be used for Fire Rated Applications.
Use of the replacement rods would void the fire rating of these flush bolts.
