Suspension line angles
Refer to WLL for M10 eyebolts and EVC loudspeakers and Suspension line angle limits for
individual eyebolts, page 13 for specific eyebolt angle and weight limitations when using
eyebolt suspension. These limits are not to be exceeded under any circumstances. If a safety
factor higher than 10:1 is required, the angle limits for each eyebolt may actually decrease to a
number less than what is shown in
Suspension line angle limits for individual eyebolts, page 13 .

Always ensure that the suspension line is in the plane of the eyebolt, as shown in Eyebolts
orientated in the plane of pull, page 11 . Readjust the eyebolt during the installation if necessary
to maintain this alignment.
