Full Coverage Non-Marring Foot Grounder

Description:

The 17270, 17271, 17272, and 17273 Foot Grounders provide contact with the ESD

floor both under the foot’s sole as well as the heel area, providing a more continuous

and reliable path-to-ground. These foot grounders are easier to install than most foot

grounders and are designed for use on standard shoes. The snug, reliable fit can be

easily adjusted to fit the individual wearer. These foot grounders are made from non-marring

three layer high visibility yellow reversible static dissipative rubber with a black conductive inner

layer. The 17270, 17271, 17272, and 17273 are all UL listed. It is a suitable ESD footwear

component in Flooring - Footwear System meeting ANSI/ESD S20.20 when used as the primary

grounding method. It meets <3.5 x 10E7 ohms per ANSI/ESD STM 97.1 Floor Materials and

Footwear-Resistance Measurement in Combination with a Person, and significantly under <100

volts tested per ANSI/ESD STM 97.2 - Floor Materials and Footwear Voltage Measurement in

Combination with a Person

Specifications and procedures subject to change without notice.

Our UL listed foot grounders are rated at 250 VAC. It is not recommended to use them where exposure to

line voltages above 250 VAC is possible. Caution: The foot grounder is for ESD control. It will not reduce or

increase your risk of receiving electric shock when using or working on electrical equipment.
