The NATIONAL MFG/SPECTRUM BRANDS HHI N330-738 is a heavy-duty handrail bracket designed to secure wooden handrails to a wall, stud, or other structurally sound surface. The bracket body is constructed from zinc die cast material, while the strap is made from steel, providing a durable assembly suited for residential and light commercial stairway applications. The oil rubbed bronze finish delivers a consistent appearance on interior installations. Both the bracket and strap are engineered to adjust to any stairway angle, eliminating the need for custom-cut hardware on angled runs. This package includes 5 brackets. Licensed contractors, finish carpenters, and building maintenance professionals handle typical installations.
This bracket is intended for stairway handrail installations where the rail must be anchored to a wall framing member or structurally sound backing. Maximum spacing between brackets must not exceed 48 inches on center. The adjustable strap design accommodates varying stair pitch angles without requiring additional hardware modifications, making it practical for both new construction and retrofit handrail projects in residential settings.
Designed as an OEM-style replacement or new-installation bracket for wooden handrail systems requiring wall-mounted support on angled stairway applications.
Installation is typically performed by a licensed contractor or finish carpenter in accordance with applicable building codes, including IRC stairway handrail requirements. Always fasten brackets into wall studs or structurally sound backing rated to support handrail loading. Power down any adjacent low-voltage lighting or intercom wiring before drilling into walls. Do not exceed 48 inches of spacing between brackets along the handrail run.
