Vintage Rim Knob Lockset

The ILC5900451 is a surface-mounted rim lockset finished in polished chrome. It suits period restorations and new builds that want a traditional skeleton-key appearance without modern cylinder hardware.

Surface Mount With Reversible Latch

The black case fixes directly to the door face so no mortising is required. A reversible latch lets the same unit serve doors that swing in or out, and the kit includes brass knobs, rosettes, escutcheon and wood screws for a complete fit.

Replaces Mortise Or Tubular Sets

This lockset upgrades doors previously fitted with mortise boxes or tubular latches where a surface rim lock is preferred. The jump is worth it when the existing door thickness or trim prevents mortising and a vintage bit-key action is specified.

Highlights

  • Vertical rim design suits period doors
  • Reversible latch fits inward or outward swing
  • Surface-mounted case simplifies installation
  • Brass knobs, rosette and escutcheon included
  • Deadbolt operates with skeleton key both sides
