303Z Vest

A safety vest made by EZ-ON Products of Jupiter, Florida.

Description

This vest is made of webbing and features an adjustable, back-closure zipper. The vest provides upper body restraint, and its back closure can be helpful in thwarting the wearer from taking it off during transport.  An adult must assist the child into the vest, ensure it is properly adjusted, seat the vest-wearing child in a vehicle seat that has an installed EZ-ON floor mount or tether mount, and attach the vest to the mount at each mounting point. 

NOTE:  For anchorage to the vehicle, this safety vest must be used with either of the model-appropriate mounts described here.

  • The floor mount (100FM) requires two tether anchors (included) to be professionally installed in the vehicle and the ability to slip the strap through the seat bight.  
  • The tether mount (100TM) requires the use of one tether anchor (can be factory-installed or purchased from EZ-ON and installed) as well as a vehicle seat belt (or LATCH lower anchors, if a separate Lower LATCH Add-on is purchased).

This vest can also be used on a school bus by utilizing a seat mount style that’s appropriate for those vehicles; however, this SRN Web resource focuses only on use in personal vehicles.
