The four pairs of quarter-turn mounting points in the base accept 106 mm (4.17 in.) center-to-center omega
brackets (see Figure 4) for rigging clamp attachment. The omega brackets can be fastened to the base
parallel to the fixture’s sides or diagonally (see Figure 3).
Installation hardware
Two omega brackets suitable for use when rigging the MAC Ultra Performance 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 Performance 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 two rigging clamps securely to omega brackets using M12 bolts (minimum grade 8.8) and
self-locking nuts.
