Metallics JR100 – Frequently Asked Questions
1) What does the Metallics JR100 reducing washer actually do on a box knockout?
It closes down an oversized knockout so a smaller connector can be used. The JR100 takes a 3/4 inch knockout down to a 1/2 inch opening, so a 1/2 inch connector or fitting can be landed in a box or enclosure that was punched for 3/4 inch. Galvanized steel construction.
2) Do I need one washer or two to close a 3/4 inch knockout down to 1/2 inch?
Reducing washers are used in pairs, one on each side of the sheet metal, so the knockout is closed from both the inside and the outside of the box. The JR100 ships as a jar of 100 pieces, which covers 50 openings at two washers each.
3) What size reducing washer do I order if my knockout is 3/4 inch and my connector is 1/2 inch?
That is exactly the JR100. It is the 3/4 inch to 1/2 inch reducer, meaning the outside steps into the 3/4 inch knockout and the inside diameter passes a 1/2 inch fitting. If your knockout or connector size is different, you need a different reducer pair, since each washer set handles one size combination only.
4) Is the Metallics JR100 washer suitable for outdoor or damp-location enclosures?
The JR100 is galvanized steel, which gives it corrosion resistance for general damp and exterior use. Keep in mind a reducing washer is not a seal: it only closes the knockout mechanically. If the enclosure has to stay raintight, the connector itself needs to be the raintight type.
5) Can plumbing or HVAC crews use Metallics reducing washers, or is this electrical only?
Metallics lists the application as the electrical, plumbing, heating and air conditioning industries, so the same reducing washers get used on mechanical enclosures and equipment panels, not just junction boxes and panelboards.
6) Are Metallics JR100 washers made in the USA?
Yes, country of origin on the JR100 reducing washers is the United States.
7) How much does a jar of 100 Metallics JR100 reducing washers weigh for MRO stocking?
The jar comes in at 0.92 lbs for all 100 pieces, so it is light enough to keep several sizes on a service van or on a shelf in the shop without eating into load.
