A touch lock (sometimes also called a “concealed lock” or “spring latch lock”) for uPVC sliding windows is a simple, often spring-loaded, locking mechanism. When the sliding sash is pushed closed, the latch or bolt on the sash automatically engages with the keep on the frame, securing the window. It usually doesn’t involve a key or a handle turn for the primary locking action; a “touch” or push to close activates it. To open, you typically press a small button or lever on the lock itself.
The “Keep” for a Touchlock:
The keep for a uPVC touchlock is typically a relatively small, simple metal or uPVC component with a slot or a recess designed to precisely receive the latch of the touch lock.
Key Characteristics and Functions:
Simplicity: Touchlocks and their keeps are designed for quick and easy operation.
Convenience: They offer fast locking simply by closing the window.
Basic Security: While convenient, touch locks often provide a lower level of security compared to multi-point hook locks found on main sliding doors. They are more common on windows or internal sliding doors where high security isn’t the primary concern.
Automatic Engagement: The keep is crucial for the “automatic” locking action, as the latch on the sash snaps into the keep when the window is closed.
Material: Keeps can be made of mild steel, aluminum, or sometimes a durable plastic (UPVC) to match the profile.
