Installation hardware
Two omega brackets suitable for use when rigging the MAC Ultra Wash are supplied with the fixture. Martin
can supply as accessories suitable rigging clamps and safety cables that are approved for the weight of the
fixture. Contact your Martin supplier for details.
Clamping the fixture to a truss
To clamp the MAC Ultra Wash to a rigging truss:
1. Check that all rigging hardware is undamaged and can bear at least six (6) times the weight of the fixture
or as required by locally applicable regulations. Check that the supporting structure can safely bear the
weight of all installed fixtures, clamps, cables, auxiliary equipment, etc. and complies with locally
applicable regulations.
2. Bolt each rigging clamp securely to an omega bracket with an M12 bolt (minimum grade 8.8) and
self-locking nut.
