ESD = Electrostatic Discharge
Quick-Disconnect
A Quick-Disconnect, located 6″ from the powder measure, makes toolhead changes possible without disconnecting the ground cord from the powder measure. Two Powder Measure Harnesses are included. Additional Powder Measure Harnesses are available so that every powder measure you own can have its own dedicated ground harness.
NEMA 5-15 Plug
The NEMA standared plug inserts into any US/Canadian 3-pin grounded wall outlet. Although the plug has three prongs, only the Ground (round pin) is connected to the wire. The Hot and Neutral (flat blades) are not connected to anything but help hold the plug securely in the outlet. The interior of the plug body is backfilled with an insulating potting compound.
Safety Surge Resistor
A 100kΩ resistor is installed inside the NEMA plug to protect from any shock if the ground accidentally becomes electrified (e.g. from a lightning strike or a short between Hot and Ground). It also prevents the possibility of a spark when reconnecting the ground cord during toolhead changes.
Highest Quality Components
This Ground Cord is custom made for UniqueTek at a US company that has been making wiring harnesses for commercial and industrial customers for 20 years. They use only high quality components and the work is done by a staff of highly skilled technicians.
Kit Includes
– 1 Ground Cord
– 2 Powder Measure Wire Harnesses^
^ Additional Powder Measure Wire Harnesses are available in 2-packs.
Q&AQ: Can this be used on other presses and powder measures?
A: Yes. Although designed with the ring lugs needed for a Dillon powder measure, it can easily be attached to many other powder measures. The photo at right shows it attached to an RCBS Quick Change Powder Measure (Model: 98840) on a Pro Chucker 7 press. In this case you need only attach the #10 Ring Lug to the CAPM Back Bracket (#7788949).

Couple of points here - WST is a known problem child for static being a small flake powder with graphite coating, unless you are in a high static environment this is unlikely to help much.
And now for the results ...
Before installing this solution, powder drops with ball pistol powders normally saw a +/- 0.10 grain variance every ~10 drops.
After installing this solution, I saw similar +/- 0.10 grain variances; but they decreased to every ~20 to ~25 drops. I also noticed that powder granules were no longer clinging to the sides of the powder measure. I think draining the powder hopper is also easier (fewer granules "hanging on" in the hopper).
A couple of notes ...
- After installation, I followed additional "tips" that were included in the instructions. Very helpful.
- Average temperature in my reloading room is 70F with average humidity of 38-45% (depending on season)
Static buildup can be very dangerous or possibly deadly, so I feel this is a very inexpensive insurance policy.
