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
Components:
A. 0.060" thick (± 0.005) non-marring, solid, three layer, rubber material. Three layers
consist of a yellow dissipative outer layer with a black conductive inner layer, and a yellow
dissipative outer layer. Will not mar floors or shoes with black marks.
B. 3/8” wide, 18” long blue nylon ribbon contains 8 electrically conductive carbon suffused
fibers, reversible, may be positioned on either side of foot.

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.
