When requesting steel windows, please specify the following where applicable:

• Whether the window frame should be manufactured from F7 or FX7 sections.
• The window hand, viewed from the inside: LH for left-hand and RH for right-hand windows.
• Burglar bar pattern, and whether bars are required for openers only or the full window.
• Fitting finish preference, such as brass or chrome-plated finish where available.
• Whether glazing is required on the inside or outside for applicable industrial, school or specialised windows.

Note: Window sizes are based on FX7 window frames. For F7 window frames, deduct 25mm from the width and height dimensions.
