Safety Information

For Permanent Installation

WARNING: Permanent installations involve the attachment of the loudspeakers to brackets or other mounting surfaces

for long-term or seasonal use. Such mountings, frequently in overhead locations, involve risk of personal injury if either the

mounting system or the loudspeaker attachment fails. Installation of the mounting system must be performed in accor-

dance with all applicable building codes including local codes. Consult the local authority having jurisdiction before install-

ing this product.

Bose offers mounting brackets for the use of these loudspeakers in permanent installations. However, we

realize some installations may call for use of other, custom-designed mounting solutions or non-Bose mounting

products. While Bose Corporation cannot be held responsible for the proper design and use of non-Bose mounting

systems, we offer the following guidelines for the permanent installation of the Bose 502

• Obtain your mounting system from a reputable manufacturer, and make sure the system is specifically designed for

the loudspeaker of choice and your intended use.

• Before using a custom-designed and fabricated mounting system, have a licensed professional engineer review the

design and fabrication for structural integrity and safety in the intended application.

• Notice that all threaded attachment points on the bottom and rear of each loudspeaker cabinet have a metric

M8 x 1.25 thread with at least 10 usable threads.

• Use a safety cable, separately attached to the cabinet at a point not in common with the load bearing attachment

points of the bracket to the loudspeaker.

• If you are unfamiliar with the proper design, use, and purpose of a safety cable, consult a licensed professional

engineer, a rigging professional, or a theatrical lighting trades professional.

CAUTION: Use only graded hardware. Fasteners should be metric Grade 8.8 minimum and should be tightened

using torque not to exceed 50 inch-pounds (5.6 Newton-meters). Overtightening the fastener could result in irreparable

damage to the cabinet and an unsafe assembly.

Lockwashers or a thread locking compound intended for hand disassembly (such as Loctite

vibration resistant assembly.

CAUTION: The fastener should be long enough to engage no fewer than 8 threads of the attachment point. Using

a fastener that is too short provides inadequate holding power and may strip the mounting threads, resulting in an unsafe

assembly. Confirm that at least 8 full threads are engaged in your assembly.

CAUTION: Do not attempt to alter the threaded attachment points. While SAE

in appearance to the metric M8, they are not interchangeable. Do not attempt to re-thread the attachment points to

accommodate any other thread size or type. Doing this will render the installation unsafe and will permanently damage

the loudspeaker. You may substitute

-inch washers and lockwashers for the 8 mm ones.
