The dual frame provides much greater strength and stability than single designs. The locking mechanism consists of two die-cast circular discs, a and b, each with complementary hill and dale surfaces. Pressing the locking handle brings both discs together and they remain firmly locked at the same angle. This product only uses locking nuts which cannot shake loose and get lost.
These stands are imported by Studiospares in container loads and sold directly to the end-user, hence the highly competitive price. The manufacturer works in accordance with the ISO 9001 quality standards.
The stand is supplied as standard without extension arms but the following optional variable angle keyboard extension arms are available:
Simply plug the expanding part into the back of the X Frame and tighten the screws. This will cause the plugs to expand securing the extension arms in place. The keyboard arms can be set at any angle by a locking system identical to the double X frame above.
The rear horizontal telescopic bar provides added rigidity.
