4 Function

This device is an adapter to allow secure connection between a Blatchford female pyramid
connector on a prosthetic limb and a prosthetic socket with a 4-bolt connection. The device
provides horizontal slide adjustment in the anterior-posterior plane, rotational and tilt
adjustment in the vertical plane.
When the adapter's 4-bolt connection screws are securely fastened to the socket, and the grub
screws on the attaching limb's female pyramid are securely fastened to the adapter's male
pyramid, then the device provides a secure connection between limb and socket.
For correct screw torque settings and Loctite application for secure connection, refer to the
Construction section for the 4-bolt connection and refer to the Instructions for Use of the
attaching Blatchford device for the pyramid connection.
