Lynrus Safety Straps help you prevent equipment falls in your gyms.

Most basketball systems are custom built at a state of the art factory and shipped as a kit to a job sight and are then reassembled and installed in the gym ceiling. Manufacturers of suspended basketball equipment are very safety conscious and build safe and reliable structures. Once the system is properly installed it is the school’s responsibility to inspect and maintain that equipment.
The one item you should have even if you inspect and maintain your suspended equipment regularly is a fully automatic safety strap. This piece of equipment acts as a backup so, that if the cable ever failed, the safety strap acts like the seat belt in your car and stops the backboard from falling. Many older safety systems were not automatic and pinched the belt when triggered requiring a manual reset of the unit. Striking the belt of an older system with a ball could trigger some of these systems leaving the basket stuck in mid air. After having to travel 30 feet high to reset the unit a few times, many were just removed from the backstop and tied off to avoid having to reset them. Today, safety straps are fully enclosed and work silently in the background and do not need to be reset if actuated. There is no good reason for any movable backstop to
not have a safety strap installed.

We can inspect the safety straps, repair them and replace them at American Athletix.  Lynrus— affordable and essential.
