Deltana 24SB3-UNL 24in Heavy Duty Surface Bolt Brass

Product Description

The DELTANA 24SB3-UNL is a heavy-duty surface bolt designed for securing doors, gates, and panels in commercial and residential applications. This 24-inch bolt is constructed for long-term reliability in high-traffic environments and ships in an unlacquered bright brass finish that retains the natural warmth of solid brass without a protective lacquer coat. At 1.8 pounds and measuring 24.8 inches in length, it provides substantial hardware presence suited to oversized doors and paired door assemblies. Installation is typically handled by carpenters, finish hardware tradespeople, or general contractors during door hardware rough-in or final trim.

The 24SB3-UNL is suited for use on double doors, barn doors, French doors, exterior gates, and large interior passage doors where a flush bolt or chain latch would be undersized. The heavy-duty construction makes it appropriate for commercial entryways, institutional settings, and residential applications requiring a robust sliding bolt mechanism. The unlacquered bright brass finish is commonly specified in projects where the hardware will be maintained or polished over time, or where a living finish is preferred by the specifier or end user.

Installation Notes

Surface bolts are typically installed by carpenters or finish hardware contractors using standard drill and screwdriver tools. Power down any electric strike or access control hardware integrated into the door assembly before beginning work. Mount the bolt body flush and plumb to the door stile, and verify strike alignment before final fastener tightening. Follow local building code requirements for door hardware on egress and fire-rated assemblies.
