How to Measure Your Ranger & Cheng Bang Window or Blind

Caravan windows and blinds are fitment-sensitive — an incorrect measurement means the wrong size. Follow these steps carefully before placing your order.

Ranger & Cheng Bang Window Measurement Guide
  1. Identify the external black frame

    Locate the outer black aluminium frame that surrounds your window from the outside of the caravan. Do not measure the glass or the inner trim.

  2. Measure outer edge to outer edge

    Using a steel tape measure, measure the external black frame from outer edge to outer edge — both the width (horizontal) and the height (vertical). Tip: Measure twice and record both dimensions in millimetres (mm).

  3. Apply the -30mm deduction

    Deduct approximately 25mm to 30mm from both the width and the height to get your blind/screen size. The deduction can vary between 25mm and 30mm depending on the fitment. Example: External frame measures 930mm × 480mm → deduct 30mm from each dimension → order size is 900mm × 450mm.

  4. Find your product code

    Our product codes follow the format RFW[Width][Height] (e.g., RFW900450 = 900mm wide Ă— 450mm high). Match your calculated dimensions to the correct variant in the product listing.

  5. Quick Reference

    Side Window Blind / Screen: Measure the external black frame outer edge to outer edge, then deduct 30mm from the width and height. Complete Window Unit: Measure the external black frame outer edge to outer edge, then deduct 30mm from the width and height.
