Metallics R122 – Frequently Asked Questions
1) What size knockout does the Metallics R122 reducing washer adapt?
The R122 reduces a 4 inch knockout down to 2-1/2 inch conduit or fitting. In practice you use it when the box or enclosure was punched for a larger trade size than the raceway you are actually landing, so the connector or hub still seats tight against the sheet metal.
2) Do reducing washers come as a pair, and how many are in a box of the Metallics R122?
Reducing washers are used in pairs, one on each side of the enclosure wall, so the fitting is clamped between them. The R122 is packaged as a box of 10 pieces, which covers five openings if you are doubling up on every knockout.
3) What material are the Metallics R122 reducing washers made of, and can I use them outdoors?
Galvanized steel. The zinc coating handles damp and wet locations and outdoor enclosures better than plain steel, and it keeps the washer in the same metallic family as a steel box or rigid conduit so you are not creating a dissimilar metal joint at the knockout.
4) Are reducing washers the right fix for an oversized knockout, or should I use a closure plate?
Two different jobs. A reducing washer like the R122 is for a knockout you still need to run conduit through but that was punched one or more trade sizes too large, here 4 inch down to 2-1/2 inch. If the opening is not being used at all, you want a knockout seal or closure plug instead, not a reducer.
5) What part number do I order for a 2-1/2 by 4 inch Metallics reducing washer?
Order Metallics R122. That is the manufacturer part number for the 2-1/2 by 4 inch galvanized steel reducing washer, sold in a 10 piece box. Metallics numbers the reducing washer line by the two trade sizes it bridges, so adjacent numbers cover other size combinations.
6) How much does a box of Metallics R122 reducing washers weigh, and what are the carton dimensions?
The 10 piece box runs 3.25 lbs and measures 7.25 by 6.75 by 3.25 inches. Worth knowing if you are staging material for a panel or gutter installation and counting weight on a lift or a service van shelf.
