Casement Handle With Key

Casement Handle With Key

A casement handle with a key is a type of handle used on casement windows that includes a key-operated locking mechanism. This provides an extra layer of security compared to handles without keys, preventing the window from being opened by simply turning the handle.  

Here’s what you need to know about them:

How They Work:

  • Operation: Like standard casement handles, turning the handle engages the window’s locking mechanism (usually an espag rod system with multiple locking points along the frame).
  • Locking: The key cylinder is integrated into the handle. When the key is turned, it throws a small bolt or engages a block that prevents the handle from being rotated. This secures the multi-point locking system in the engaged position, making it much harder to open the window from the outside.

Benefits of Casement Handles with Keys:

  • Enhanced Security: The key provides an additional barrier against forced entry, offering greater peace of mind.  
  • Child Safety: Locking the handle can prevent children from opening windows and potentially falling out.
  • Ventilation with Security: You can often slightly open the window for ventilation and then lock the handle with the key in that position (depending on the handle design).
  • Deterrent: The visible key cylinder can act as a deterrent to potential intruders.
