The E-Z-On Adjustable Vest, model 103Z, is a harness restraint designed for use with children and adults with physical, balance, emotional, or behavioral disabilities. This restraint prevents the wearer from leaving the vehicle seat or wheelchair and provides additional support to keep the wearer in an upright position. Designed to be used in a van, bus, family vehicle, or with a wheelchair, this parachute-style harness comes standard with back zipper closure to prevent the wearer from removing it. One-pull adjustments lengthen the vest to ensure proper strap positioning over the lap area. Sherpa fleece neck pads have Velcro closure to provide access to slide buckles. Bar slides help deter the wearer from loosening the adjusters. Built-in zippers enable the chest and waist straps to be adjusted to accommodate growth and heavy clothing. SIZES: Children's extra small, small, small medium, or medium and adult medium large, large, extra large, and extra extra large. OPTIONS: Front closure with push button, front closure with buckle rings, back closure with Velcro, portable seat mount, permanent floor mount, tether strap mount, and a wheelchair mount. Also available are additional sherpa neck straps, zipper inserts, anke restraints, wrist restraints, and more.
