Electrical

Solar Panel Chargers for Large-Cell Batteries

Keep batteries charged even when electricity is unavailable.

Power Cords for Large-Cell
Battery Solar Panel Chargers

Connect a flexible solar panel charger to a vehicle outlet.

UV-Resistant Wire

Also known as photovoltaic (PV) wire, this wire won’t deteriorate from UV light when used outdoors. It’s often used in solar panels.

High-Voltage Continuous-Flex Wire

Use this wire in automated applications that require 14,000 volts A/C or greater. It withstands continuous motion without degrading data or signal transmission.

Building and Machinery Hardware

Strut Channel Panel-Mounting Brackets

Clamp panels onto strut channel to hold them in place.

Aluminum Slip-On Framing and Fittings

Half the weight of steel, this aluminum framing resists corrosion in wet environments.

Sealing Corner Brackets

A rubber seal protects against moisture around the installation hole.

Lighting

Solar-Powered Motion-Sensing Security Lights

Powered by the sun, these security lights function in areas that don’t have access to electricity. They’re often used to shine light on parking lots, landscaping, signs, entryways, and other outdoor spaces.

Meters for Solar Power Systems

Find the best spot for new solar panels or check the performance of existing ones.

Solar-Powered Flashing Lights

Place these lights in full sun and their batteries charge during daylight hours. Lights automatically switch on at dusk and off at dawn.

Solar Flagpole Lights

Illuminate outdoor flags without connecting to an electric power source. These lights have a built-in solar panel that gathers energy from the sun throughout the day to power them at night.

Adjustable-Angle Solar-Powered Threaded Thermometers

Adjustable-Angle Solar-Powered
Threaded Thermometers

Since these thermometers operate on indoor light, there’s no need for batteries. They pivot 180° to support angled mounting.

Calculators

Metal- and X-Ray-Detectable Calculators

Made with metal and chemical additives, these calculators trigger metal detectors and X-rays if they fall into your food line, helping you comply with Hazard Analysis and Critical Control Point (HACCP) programs for food safety.

Welding Helmets

Auto-Darkening Welding Helmets

Protect your eyes the moment you start welding—four sensors detect the light and automatically darken the lens.

Precise-Shade Auto-Darkening Welding Helmets

Take full control of your shade level with these helmets—you can set the lens to adjust in half-shade increments. They have digital controls behind the lens where you can set the shade number, delay time, and sensitivity.

Low-Profile Auto-Darkening Welding Helmets

Also known as pancake welding helmets, these helmets have a flat face so you can get close to your welds. The instant you start to weld, the lens darkens.
