Weight 3.0 lbs per standard set (Solid, heavy-weight structure)
Technical Preparation & Installation

Door Preparation Fits standard pre-drilled North American doors with a 2-1/8″ cross bore and a 1″ edge bore.

Mounting System Heavy-duty concealed machine screws for a seamless architectural look.
Tool Warning Installation requires hand tools only.
Never use power tools or impact drivers — this may strip internal threads or snap screw heads.
Mechanical Engineering & Functionality
Chassis & Spring Mechanics Grade 2 heavy-duty tubular chassis with independent heavy-duty springing that keeps the knob returning true and prevents loosening over decades of use.
Acoustic Control Integrated anti-friction polymer insert in the latch bolt for nearly silent closing while reducing wear on the metal strike plate.
Available Configurations
  • Passage & Privacy — Both functions share the same rosette and standard door preparation. The Privacy set adds an integrated locking pin housed within the rosette; a simple press engages the lock for bedrooms and baths — no secondary hardware or specialized milling required.
  • Half Dummy — Stationary set for one side of a door, surface-mounted using wood screws.
  • Double Dummy — Symmetrical non-operating knobs on both sides, through-bolted using existing bore holes to withstand heavy pulling forces.
Material & Finish Technologies
Material Composition Solid Forged Brass. Excludes inferior zinc alloys, aluminum, or hollow pot metals.
Finish Technologies
  • PVD (Physical Vapor Deposition) — Vaporized metals bond to the brass substrate in a vacuum chamber, creating an impenetrable layer with extreme corrosion resistance. Ideal for high-traffic or coastal applications.
  • Lacquered & Electroplated — Protected by a highly durable, industrial-grade clear lacquer baked at low temperatures to prevent the underlying brass from oxidizing.
  • Living Finishes — Unlacquered finishes (such as Natural Brass or Oil-Rubbed Bronze) are designed to interact with the environment, oxidizing and developing a dynamic, unique patina over time.
Certifications & Warranty Data
Compliance & Safety
  • 20-minute certified UL fire-rated option available.
WARNING: This product can expose you to chemicals including lead and/or wood dust, known to the State of California to cause cancer and birth defects or other reproductive harm.
Door Handing Guide
Door handing diagram showing left-hand and right-hand configurations

Stand at the exterior side of the door, facing in. If the hinges are on the left, the door is left-handed. If the hinges are on the right, the door is right-handed.

The Pulse Knob by BEX wraps its drum in a crisp coin-edge knurl and recesses the face into a shallow machined dish framed by a raised rim — texture that gives fingertips immediate purchase, with the stepped face of a finely made instrument. Sized at 2-5/16 inches across, the solid brass Pulse pairs with the Halo, Square, Rectangular, and Bexley rosettes and energizes modern industrial spaces and design studios.

The Pulse's knurl and dished face are machined straight into solid brass, edges left crisp by hand-finishing rather than softened by plating.
