Protect Your Utility Crew and Maximize Torque Control on Live-Line Systems with 1000V Dielectric Certified Box End Wrenches

Defend your high-voltage utility workspace and execute heavy structural fastening tasks smoothly using the professional-grade Klein Tools 47140INS 8-Piece 1000V Insulated Box End Wrench Set. Meticulously engineered for certified lineman crews, commercial industrial electricians, plant maintenance specialists, and power grid contractors, this master utility array completely eliminates live-line touch hazards where there is absolutely no room for error. Working with unrated basic mechanical wrenches or generic metal options near energized transformer busbars, overhead switch gears, or active underground feeder banks introduces a massive hazard of violent arc-flash overs and contact shock. This heavy-duty Klein installation set counters those tactical safety limits directly, wrapping every structural tool frame in a proprietary three-part insulation shield designed to thoroughly isolate hands from current surges pulsing up to 1000 volts.

Forged from rugged industrial-grade tool steel and finished with an advanced overmolded plastic protective matrix, this 8-piece master layout includes the most commonly used utility sizes ranging from 3/8-inch up to 13/16-inch to satisfy your essential infrastructure tasks. Every component incorporates a specialized stepped-down box end design that provides greater physical clearance and wrench placement access in hard-to-reach, confined terminal configurations. To preserve field handling control, the set features oversized handles specifically optimized to deliver immense rotational torque and a secure non-slip grip when operated while wearing thick Class 2 electrical safety gloves. Complete with a built-in white wear indication layer that instantly alerts crews when the insulation has been structurally compromised, the entire set packs away into a foam-lined heavy-duty carrying case to stay perfectly protected and ready for your next field assignment.

Key Features

  • ASTM F1505 Certified Three-Part Insulation: Purpose-built for high-voltage live-line operations up to 1000V with absolute shock isolation parameters.
  • Visual White Wear Indicator: Inner warning core layer alerts linemen immediately if the outer dielectric polymer coating becomes compromised or scored.
  • Oversized High-Torque Handles: Custom grip profiles engineered specifically to maximize leverage and handle comfort while wearing bulky Class 2 safety gloves.
  • Stepped Box End Profile Design: Clever angled geometry offsets the wrench face, granting seamless access to deeply recessed bolts and tight nuts.
  • Foam Lined Heavy-Duty Case: Premium rugged outer shell housing holds all eight pieces securely in dedicated slots to ensure clean jobsite storage.

Pro-Tip: To safely protect the multi-layer overmolded insulation on these box end wrenches, never strike the wrench frame with a hammer or mallet to break loose rusted or frozen fasteners. Sharp high-velocity impact shocks can crack or slice the dielectric polymer layer, exposing the underlying bare tool steel core. Instead, ensure the box end loop sits completely flush and square over the bolt head to smoothly distribute your physical turning torque while keeping your bulky Class 2 safety gloves well clear of sharp frame edges.

Slightly challenging build
Color: Beige, Size: A-88''W-4 Panel
This was my second screen set I've purchased, first of this style. Not the easiest to assemble. Lots of pulling and tugging; not a highlight in my day.

Commercial grade divider suitable for many needs
Color: Beige, Size: A-132''W-6 Panel
This item will be used at a future event where we need to separate a single locker room into two large areas, without any construction. This divider is perfect for the job because the partitions can be 1 to 6 panels and it will roll into place. When the event is over, the divider will fold/roll away and the locker room will return to its original design. The unit is very heavy, which will ensure that it is sturdy and stable. All the components arrived, wrapped in plastic to prevent damage. The screen material is a woven polyester in a cream color that will occlude any visibility but it may be possible to see shadows on the opposite side. The height is about 6ft, which would require a very tall person to "peep over" the divider. I needed a quality unit for this project and the frame, screens, and mobility will meet the needs. The divider is not the same as the small decorative dividers -- it is more of a commercial grade product, yet tasteful. If you want/need a small divider as an accent piece, this is not the best choice. This item could be used in a medical office, treatment/massage room, to divide an office room into two, or block a hallway in a building.

Great option for a professional looking backdrop
Color: Black, Size: B-102''-3 Panel
I decided to try these wall dividers for my home office space since it does not have a door. I wanted to have my video calls without the rest of the room in the feed to give it a more professional feel. These being on castors make them super easy to move into position and roll off to the side when not in use. They are stable, much more than the folding screens I have tried in the past. That they are connected by the middle piece and not the top/bottom of each other allows you to adjust the positioning to your needs. Overall, this did exactly what I needed and was an affordable option. I also like that they are highly portable: if you want to take them for a booth or event, the poles all disassemble into manageable lengths that easily fit in a car and take very little time to set up again. The only thing I would change is to include a bag to store them in for transportation.

Sturdy, Easy to Set Up, and Looks Great
Color: Grey, Size: 34" - 3 Panel
I’m really happy with this RANTILA 3-panel room divider. It was simple to set up, stands securely on its own, and gives plenty of privacy. The height is perfect, and the panels look clean and modern in my space. It’s lightweight enough to move around but still feels sturdy. Overall, a great divider that works exactly as I needed.
