TRUBLUE Auto Belay Product Notice Regarding Proper Use
It has come to the attention of TRUBLUE Auto Belays that the TRUBLUE Auto Belay has been used as a zip line braking device. This is not an approved usage of the TRUBLUE Auto Belay, and its use as such can result in serious injury to participants.
It has been demonstrated in laboratory testing, that when such an impact deceleration load is applied to a TruBlue, the device brakes far too severely and may result in:
1. Potential injuries to participants (related to rapid decelerations), and/or
2. Damage to the device, potentially rendering it inoperable.
Use of the TRUBLUE Auto Belay in this manner renders the warranty void.
