Thomas & Betts 3715-TB – Frequently Asked Questions
1) What is the Thomas & Betts 3715-TB and what is it used for?
The 3715-TB is a steel reducing washer used with rigid and IMC conduit fittings. Reducing washers go in pairs on either side of a knockout so a smaller trade size conduit or fitting can be landed in a larger opening in a box, panel, or enclosure. They are a sizing accessory, not a connector, so you still need the conduit connector or locknut itself.
2) Are the Thomas & Betts 3715-TB reducing washers steel or plastic?
Steel. That matters on rigid and IMC runs where the enclosure knockout is part of the equipment grounding path and where a plastic or fiber washer would not carry the mechanical load of a metal conduit termination.
3) Do I need one reducing washer or two to fill an oversized knockout?
Two. Reducing washers like the 3715-TB are used as a set, one on the outside of the enclosure wall and one on the inside, so the fitting is centered and the opening is closed on both faces. Order quantity accordingly for each knockout you are reducing.
4) Can I use the 3715-TB reducing washers with EMT connectors, or only rigid and IMC?
They are catalogued for rigid and IMC conduit fittings, and that is the application to specify them for. What actually governs the fit is the knockout size and the trade size of the fitting hub landing in it, not the raceway type, so match the washer to the knockout and fitting sizes on your job rather than assuming from the conduit type.
5) What part number should I give my distributor for Thomas & Betts reducing washers?
Thomas & Betts 3715-TB is the manufacturer part number for this steel reducing washer, and it is the number to quote for a reorder or a submittal.
