Many circuit breaker manufacturers have introduced a rocker handle style breaker that is installed with either screws or snap-ins. APM Hexseal offers two styles to fit these breakers, with or without side finger guards. These boots come standard with #6-32 x 3/8 inch long screws. APM can supply metric mounting screws as well. Customers will need to make sure they specify thread size, screw length and drive preference (slotted or Phillips). For snap-in breakers, several sizes are offered.
