The DELTANA 8SB5 is a heavy-duty surface bolt designed for securing doors, gates, and shutters in both residential and light commercial applications. It mounts directly to the door face or edge, providing a positive latching action without a mortised cutout. The bolt ships in an Antique Brass finish, making it a practical fit for traditional and transitional door hardware sets. At 9.1 inches in overall length and 0.9 pounds, it is sized for full-size door panels and carries enough mass to deliver reliable, long-term performance under frequent use. Licensed locksmiths, carpenters, and door hardware installers are the typical trades handling this type of fitting.
Surface bolts of this type are commonly installed on double-door sets, French doors, barn doors, utility room doors, and exterior gate applications where a secondary locking point is needed. The 8SB5 is appropriate for residential entry and interior applications as well as light commercial door assemblies. Its heavy-duty construction suits high-cycle installations such as retail entry pairs or meeting-room door sets where a flush bolt or mortise solution is not practical.
Designed as an OEM-style surface bolt replacement or new-installation fitting for standard residential and light commercial door assemblies where a face-mounted barrel bolt is required.
Surface bolts are typically installed by carpenters, door hardware technicians, or licensed locksmiths using standard hand tools and a drill. Before installation, verify door alignment and strike placement to ensure the bolt seats fully without binding. Fasten securely into solid door material or backing block rather than into hollow-core facing alone. Confirm that the bolt travel clears the door frame and strike without interference before final fastener torque.
