National Hardware N330-738 Handrail Bracket Adjustable

Product Description

The NATIONAL HARDWARE N330-738 is a wall-mount handrail bracket designed to secure a wooden handrail to a wall stud or other structurally sound surface. Part of the 112 series, this bracket features a zinc die-cast construction and an adjustable strap that accommodates any stairway angle without requiring separate angle-specific hardware. The result is a single SKU that works across varied stair pitches, reducing the need to stock multiple bracket styles. Installers in residential and light commercial settings will find this bracket straightforward to fit during new stair construction or handrail replacement work.

This bracket is suited for interior stairway applications where a wooden handrail must be anchored securely to a framed wall. It is appropriate for both new construction and retrofit installations. The adjustable design makes it practical across a range of common stair rise-and-run configurations without modification. General contractors, carpenters, and finish trades typically install this type of hardware during stair framing or trim-out phases of a project.

• Bracket and strap adjust to any stairway angle — no angle-specific SKU required
• Zinc die-cast construction for durability in interior applications
• Designed to mount to a wall stud or other structurally sound surface

Installation Notes

Installation should be performed by a qualified carpenter or finish tradesperson following applicable local building codes and IRC handrail anchorage requirements. Locate and fasten to a solid wall stud or structurally sound backing — do not fasten solely to drywall or plaster. Adjust the strap to match the stairway angle before final tightening. Confirm all fasteners are fully seated and the handrail does not exhibit lateral movement before returning the stair to service.
