The bracket is designed for a large, and therefore heavy TV set. But at the same time, tilt adjustment is only by clamping the sector in the desired position. But to catch the TV set in this position alone is not realistic: it is heavy and fixed with a shoulder of 10 cm between the center of gravity and the axis of rotation - i. E. creates a large moment to tilt down the screen. A penny worm pair instead of two installed sectors would solve the problem.
