Ives FB358 US26D – Frequently Asked Questions

1) What is the Ives FB358 flush bolt used for?
The FB358 is a manual flush bolt designed to secure the top or bottom of double doors. It provides positive locking when one door leaf needs to remain stationary while the other operates as the active door.
2) Can this flush bolt work on both top and bottom door positions?
Yes, the FB358 is designed for installation at either the top or bottom of the door. The same hardware accommodates both positions with proper mounting orientation.
3) What door thickness does the FB358 accommodate?
Verify the door thickness compatibility with the manufacturer specifications. Most Ives flush bolts accommodate standard commercial door thicknesses, typically 1-3/4" to 2-1/4".
4) Is this flush bolt suitable for fire-rated door assemblies?
Check the product labeling and fire rating documentation. Fire-rated applications require specific listings and proper installation per the manufacturer's fire rating requirements.
5) What finish options are available for the FB358?
The FB358 is available in multiple finishes to match door hardware. Common options include satin chrome, oil rubbed bronze, and bright brass. Verify available finishes for your specific model.
6) Does this flush bolt meet ADA accessibility requirements?
Manual flush bolts on inactive door leaves typically do not conflict with ADA requirements since they're not part of the primary egress path. Consult local codes for specific accessibility compliance.
7) What tools are needed for FB358 installation?
Installation typically requires a drill, appropriate drill bits, chisel, screwdriver, and measuring tools. Follow the manufacturer's template for precise mortising and hole locations.
8) How do you adjust the bolt throw on the FB358?
The bolt throw is typically factory-set for standard applications. Field adjustments may be limited. Ensure proper strike alignment and door gap clearances during installation for optimal operation.
9) Can the FB358 be used with automatic door operators?
This manual flush bolt is designed for inactive door leaves. If automatic operation is needed, consider electric flush bolts that integrate with access control systems and automatic operators.
10) What are common alternatives to the FB358 flush bolt?
Alternative solutions include other door hardware options like surface bolts, coordinator systems, or electric flush bolts depending on operational requirements and security needs.
11) How do you maintain the FB358 flush bolt?
Regular maintenance includes cleaning debris from bolt channels, light lubrication of moving parts, and checking mounting screw tightness. Avoid over-lubrication which can attract dirt buildup.
12) What door weight capacity does the FB358 support?
Verify door weight specifications with manufacturer documentation. Proper installation and adequate door frame reinforcement are essential for supporting heavier commercial doors safely.
