Onslow Long Plate Sprung Door Knob & Thumbturn

Bronze  16178

Product discontinued

Our flat-fronted Onslow door knob is a contemporary alternative to our beehive design.

This version includes a low-profile, long backplate with a built-in thumbturn.

The knob is sprung, which means you don’t need to rely on the latch's spring for its movement.

There’s also no danger of it coming away in your hand – the spindle is threaded onto the knob which holds it in place.

Bronze is our boldest finish, but it isn’t shiny or bright, so it has a subtle side to it too. It’s a deep matt brown colour that’s almost black in some lights.

  • Solid brass 4mm backplate with screwless ‘front’ side
  • Super smooth turn thanks to self-lubricating, high-tolerance bushings
  • Longer handle neck for a comfortable grip (compared to rose variant)
  • Sold in a pair
  • Must be installed using our 12mm template profiler router bit and flat plate routing jig

Because our backplates are just 4mm in depth, we’ve designed the handle’s spring mechanism to recess into your door. You’ll need our 12mm template profiler router bit and flat plate routing jig to get the square pocket for the mechanism just right.
