Crescent Apex eSHOK-GUARD

eSHOK-GUARD Accessories Give Pros Protection Up to 1,500 Volts

According to Crescent, 54% of Pros work around live electricity every single day. On top of that, 62% use battery-powered impact tools to carry out their electrical work and 87% have been shocked while on construction sites. That’s a lot of electrical hazards. Because so much potential exists for injury, Crescent Apex developed eSHOK-GUARD Bit Holders and Socket Isolators to help keep Pros safer.

Crescent Apex eSHOK-GUARD Bit Holders and Socket Isolator Overview

Most tools in this category provide insulation, not isolation. You can’t understate the difference. One offers some protection up to particular voltage and current ratings—the other simply provides a disconnect from the danger potential. Crescent Apex eSHOK-GUARD power tool accessories are the only power tool accessories we’re aware of on the market that actually isolates an electrical current. This prevents it from ever reaching the person using it. We quickly became curious as to the design and how well these accessories might hold up under normal use.

Ideal for Electrical Work

Crescent Apex has designed the eSHOK-GUARD Bit Holders and Socket Isolators for work involving circuit breakers, appliance installation and repair, HVAC system work, junction boxes, outlets, switches, and other live wire applications. In short, they have a wide variety of potential applications. All of those applications can provide some level of potential for electrical conductivity to the user.

Just how the Crescent Apex eSHOK-GUARD Bit Holders and Socket Isolators provide safety while working with electricity piqued our interest. Of note, all of these accessories have been UL classified for isolation of up to 1,000 volts DC and 1,500 volts AC.

The Crescent Apex eSHOK-GUARD Isolated Bit Holder

The Crescent Apex eSHOK-GUARD Isolated Bit Holder looks much bigger than any bit holder you typically use in the field. It features a magnetic tip to hold your fasteners securely in place. A retaining ring lets you hold onto and replace bits easily, and the 1/4″ hex shank ensures that you can use it with your impact drills and drivers.

But what about nut-driving? Well, the 1/4″, 3/8″, and 1/2″ Crescent Apex eSHOK-GUARD Socket Isolators provide a compact, impact-rated design for heavy usage in impact applications. That actually surprised us since Apex managed to combine electrical isolation with impact-ready durability. The socket isolators use a ball detent retention system to make it easy to switch sockets.


For the price, these seem like a no-brainer addition to any electrician’s toolbox. You may not prefer using them over traditional bit extenders due to their increased girth—but you will know when to pull them out to keep you safe. It seems very clear these offer a level of protection that gets you one more step away from a shock hazard. In our book—that makes it a great development for the electrical field.
