MOUNTING THE LFA 3.1 OR 4.1 ARM TO THE WALL-MOUNTING BRACKET

The rotating hinge of the arm comes in three pieces: Metal rotating hinge, red plastic ring, and clamping pin. Refer to Figure 3. Mount the red plastic ring to the metal rotating hinge by fitting the clamping pin through the hole in the rotating rod, and snapping it into place on the U-shaped indents on the red plastic ring. The lip of the ring should fit securely against the top edge of the rotating flange, yet rotate with the rod. The assembly should look like Part C in Figure 4.
