- Use a Single Tether (44" long) with the RideSafer, a lap-only seat belt and children 30-60lbs.
- Use a Dual Tether (84" long) with the RideSafer, a lap-only seat belt and children 60-80lbs. Vehicle tether anchor points are only rated by the car manufacturer to 65 lbs. so for children who are between 65-80 lbs and using a lap only belt, we are required to split their weight between two tether anchor points or with two EATALs (sold separately).
When using the tether and the lap and shoulder belt, because the seat belt is doing the vast majority of the upper body restraining and not the tether, they can use the single tether all the way up to the 80 pounds. The dual tether is only required when the vest is doing all the restraining in a lap only belt situation.
