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

    ARTICLE NO.172 | Why Your Handle Turns but the Door Won't Open

    You press the lever down. The handle moves through its full arc with normal resistance. The familiar click of the latch retracting reaches your ears. Yet when you push or pull, the door refuses to budge. The handle has done its job—or at least it has gone through the motions—but somewhere between the lever and the latch, the mechanical chain has broken. This situation is both frustrating and diagnostically specific. The fact that the handle moves normally narrows the possible causes to a defined set of mechanical failures, each located at a different point in the path from hand to bolt.

    ARTICLE NO.171 | The Static Load Capacity of a Window Stay vs. Its Dynamic Load Capacity Under Wind Gusts

    A window friction stay is rated to hold a sash of a certain weight at a certain opening angle. This rating, typically expressed in kilograms, appears straightforward. A stay rated for 20 kilograms should hold a 20-kilogram sash. But this number represents static load capacity—the ability to support a stationary sash under calm conditions. The real world is rarely calm. Wind gusts impose loads that are fundamentally different from the steady weight of the sash, and a stay that is perfectly adequate under static conditions can fail dramatically when subjected to the dynamic forces of a storm. Understanding the distinction between these two loading regimes is essential for anyone who specifies, installs, or relies on friction stay hardware.
