300mm or 600mm extension strap - ideal when you need that extra tether strap length during installation.
Some vehicles require an extension strap to allow a tether Strap or upper anchorage strap on a child restraint to be connected to the child restraint anchorage in the vehicle - usually station wagons or 4wd.
Extension straps are available in 300mm and 600mm lengths to suit most vehicles and child restraints.
