Amerock AM Westerly 1-3/16″ Black Bronze Cabinet Knob

The Amerock Westerly cabinet knob delivers die-cast zinc construction with a lifetime warranty at a 4.8-star rating across 1,755 reviews. At 30mm diameter and 0.16 pounds, it offers substantial feel without overwhelming cabinet doors. The transitional style bridges traditional and modern designs, while the Black Bronze finish features copper brush marks for depth.

This knob works best for contractors handling both residential remodels and light-commercial builds where durability matters. The limited lifetime warranty covers defects in materials and workmanship for the original purchaser — valuable protection when installing hardware in rental properties or vacation homes.

Construction and Installation Details

The die-cast zinc construction stands up to Montana’s temperature swings better than pot metal alternatives. At 73 grams, the knob has enough heft to feel quality without straining cabinet doors. The base measures 21mm x 21mm, providing stable mounting on both overlay and inset cabinet styles.

Installation stays straightforward with two included screw lengths — a standard 1-inch #8-32 for typical 3/4-inch cabinet doors and a 1.5-inch option for thicker doors or drawer fronts with sub-fronts. The process involves aligning the knob with pre-drilled holes, inserting the appropriate screw, and tightening with a Phillips-head screwdriver. No special tools needed.

Finish Options and Design Flexibility

The Black Bronze finish combines dark tones with copper brush marks, creating visual interest without shouting. Eight total finish options let contractors maintain consistency across projects — Champagne Bronze, Golden Champagne, Graphite, Oil-Rubbed Bronze, Polished Nickel, Satin Nickel, and Polished Chrome round out the collection.

The transitional style works equally well on shaker cabinets in a Whitefish ski home or traditional raised-panel doors in a Great Falls ranch house. Unlike ultra-modern hardware that dates quickly, this design has staying power. Contractors appreciate coordinating with other Westerly collection pieces — no mixing and matching from different product lines to achieve a cohesive look.

The Bottom Line

Worth buying for kitchen and bath remodels where clients want proven quality over basic hardware alternatives. Die-cast zinc construction handles Montana’s humidity swings from wood stove heating better than cheap alloys. The lifetime warranty protects against manufacturing defects — though normal wear, misuse, and corrosive conditions aren’t covered.

For rentals or spec homes where simplicity matters, consider whether the warranty and material quality align with project goals. But for custom homes and quality remodels, the substantial feel and eight finish options justify the selection. That 4.8-star rating from over 1,700 reviews suggests contractors and homeowners alike find value in paying for zinc over pot metal.

FAQ

What size drill bit do I need for installation?

Most cabinet doors come pre-drilled with standard 3/16-inch holes. The included #8-32 screws fit these standard holes. For new installations, drill pilot holes slightly smaller than the screw diameter.

Can these knobs work on drawers and doors?

Yes. Applications include kitchen cabinet doors and drawer fronts, bathroom vanity cabinets and drawers, pantry and furniture hardware, plus residential or light-commercial cabinetry. Use the 1.5-inch screw for thicker drawer fronts.

How does Black Bronze compare to Oil-Rubbed Bronze?

Black Bronze features copper brush marks for depth and a slightly textured finish. It reads darker and more contemporary than traditional Oil-Rubbed Bronze, which typically has more brown undertones. Both resist fingerprints well.

Are these knobs ADA compliant?

No specific ADA, Lead-Free, or Prop 65 certifications are mentioned on primary product pages. Contractors working on commercial projects should verify compliance requirements with local codes.
