A curtain rod joiner works by providing a concealed internal connection between two sections of curtain rod.
Here's a breakdown of how it works:
-
Internal Placement: The joiner is designed to slide inside the hollow ends of the curtain poles being connected. According to the reference, the Internal curtain pole joiner for 19mm (3/4") diameter poles simply slides internally into the ends of each curtain pole that are being joined together.
-
Concealed Connection: Because the joiner sits inside the poles, it remains invisible once installed, maintaining a seamless look for the curtain rod. The reference notes that the colour of the joiner will not be seen.
-
Friction Fit: The joiner relies on a snug, friction fit within the curtain poles to hold them together.
-
Sizing and Adjustment: The reference mentions that the diameter of the pole joiner can be slightly adjusted if needs be for a better fit. This suggests that minor adjustments might be possible to ensure a secure connection, potentially through slight bending or filing.
In summary, a curtain rod joiner provides an easy, hidden, and effective way to connect two sections of curtain rod together to create a longer rod.
