Update interior doors with style

Enhance interior doors with the Prime-Line E 28317 mortise style fluted glass door knobs. The clear fluted glass paired with a classic bronze finish brings timeless charm while preserving everyday usability.

Elegant design meets practical function

  • Fluted glass knobs with a bronze toned base evoke vintage character.
  • 2 inch outside diameter knobs are sized for confident grip and operation.
  • Diecast bases include secure set screws for mounting to a square spindle.
  • Designed for interior mortise style doors and compatible with square drive spindle systems used in antique hardware.

What you get and what you need

  • Two 2 inch diameter glass knobs coupled to a 17/64 inch by 3 1/2 inch steel spindle with 3/8 inch threads.
  • Includes the square spindle that fits many vintage mortise locks; rosettes, latch, trim and strike plates are sold separately.
  • Finish is classic bronze to complement antique or vintage interiors.

Installation tips and care

  • Before mounting rosettes on large predrilled holes, fill the holes to provide a stable base for rosette fasteners.
  • Apply a small amount of thread locker to set screws to minimize looseness over time.
  • Handle the glass components with care to avoid cracks or chips during installation.

Notes on compatibility and projects

This hardware is intended for interior restoration projects, matching older door styles and mortise lock configurations. It is not recommended for doors with larger modern hole patterns without prep.

With its timeless look and straightforward mounting, this Prime-Line set offers a tasteful update for antique or vintage doors without compromising interior aesthetics.
