  • COMPONENT ONLY
    Designed for use with d line door levers and knobs in dummy door configurations. A rigidiser is required for proper installation.

These precision-engineered spindles are essential for adapting d line door hardware to dummy door configurations. They securely hold the lever or knob handle in place, with the rigidiser adding stability and preventing unwanted movement.

Each spindle is sold individually and can be trimmed to fit various door thicknesses. Select the appropriate spindle type based on your door's drilled configuration and hardware setup:

  • Double-Sided Dummy Door: For doors with a bored hole that goes all the way through the door thickness. This setup supports back-to-back dummy handles or a single-sided handle with a blind rose covering the other side.

  • Single-Sided Dummy Door: For doors with a fixed handle on only one side. In this configuration, the bored hole is drilled halfway through the door, leaving the reverse side intact and unexposed.

These spindles provide a reliable, adaptable solution for installing d line dummy door hardware with precision and ease.

  • Spindle Dimensions:
    • Single Sided: Suitable for door thicknesses 30-39mm, 39-48mm or 46-55mm
    • Double Sided: Suitable for door thicknesses 20-29mm or 27-36mm 
  • Rigidiser: Ø19 mm (0.7") x L 90 mm (3.5")
  • Designed for use with 8x8 mm spindles and 38 mm fixing centre roses (M5 screws)

Step-by-Step Instructions:

    • Single-Sided: For doors with a bore hole drilled halfway through. Use with single-sided dummy handles.
    • Double-Sided: For doors with a bore hole drilled straight through. Use for back-to-back dummy handles or single-sided setups with a blind rose.
  • General Installation Notes:
    • Drill Ø19+ hole in the door to a length of 90 mm for rigidiser installation.
    • Ensure correct alignment of lever handles for a secure fit.
