Features Blind Joint Parts	Stable fastening is possible from two points. This is the strongest fastening possible with blind joints.	This blind joint can be used for a variety of purposes, such as extending frames or attaching to plates.	The plate allows for reliable and inexpensive connection.	Since the additional D hole does not penetrate all the way to the flat surface, this is a blind joint with particularly excellent aesthetics.	This is the most common blind joint that can be used with a wide range of aluminium frames.
