  • ARTICLE NO.175 | Why Your Window Stay Is Hard to Move After Painting

    Painting a window frame is a routine maintenance task that can unexpectedly disable the hardware. The window friction stay is particularly vulnerable because its mechanism operates with tight clearances and depends on clean, uncontaminated surfaces to function. A single careless pass with a paintbrush can deposit paint where it does not belong, transforming a smoothly operating stay into a stiff, jerky, or completely immovable mechanism. Understanding where paint causes problems, how to prevent paint contamination, and what to do when paint has already found its way into the stay can save both the hardware and the window from permanent damage.

  • ARTICLE NO.174 | How Corrosion Products Accelerate Friction and Wear in Stainless Steel Stays

    Stainless steel is chosen for a window friction stay precisely because it resists corrosion. The chromium oxide layer that forms spontaneously on its surface protects the underlying metal from the oxidation that rapidly degrades ordinary steel. Yet stainless steel is not immune to corrosion, and when it does corrode, the products of that corrosion become agents of accelerated wear. The very substances that signal corrosion has begun—the rough, discoloured patches on the track, the orange staining around rivet heads—are not passive indicators of damage. They are active participants in a self-reinforcing cycle that increases friction, concentrates stress, and progressively destroys the precision surfaces on which the stay depends.

  • ARTICLE NO.173 | How to Choose a Handle That Matches Your Door Thickness

    A door handle must do more than look right and feel comfortable in the hand. It must fit the door on which it is installed, and the most critical dimension in that fit is the door thickness. A handle designed for a 35-millimetre door will not necessarily work on a 44-millimetre door, and attempting to force the fit creates problems ranging from poor operation to complete functional failure. Matching the handle to the door thickness is not complicated, but it requires understanding which dimensions matter, how the spindle interacts with the door, and what adjustments are available when standard sizes do not align.
