This requirement resulted from a Consumer Product Safety Commission study that reported alleged injuries in the home caused each year by children attempting to insert foreign objects into receptacles. As a long-time manufacturer of tamper-resistant devices, we are pleased to be at the forefront of this safety measure with an expanded product line encompassing a wide range of devices in Residential and Commercial Grades.
