Buying Guide

What should you consider when choosing a surface-mount door knob?

  • Door type and mounting: Interior doors vary from surface-mounted to mortised. If you have an existing mortise or prefer a vintage look, the Prime-Line E 2478 may be ideal.
  • Backset and thickness: Ensure the product fits your door thickness (typically 7/8″ to 2-1/4″ or similar). Adjustable options help with compatibility across doors.
  • Handing and orientation: Some vintage sets require correct interior-side orientation; verify handedness before purchase.
  • Style vs. function: Dummy picks like the Kwikset Cove are for pull doors without latches, while rim locks offer privacy without high security.
  • Material durability: Brass and bronze finishes resist wear in interior environments, while iron offers rugged vintage appeal for certain doors.
  • Installation complexity: Surface mounts are generally easier for DIY; mortise-based pieces demand more carpentry or professional installation.
