Utility purchasing runs on standards, approved parts lists and bid schedules. We set up to make substitution a like for like review, not a new qualification.
- Like for like crosses. Every product page shows the Burndy, Hubbell, NSI or ILSCO number it replaces, the die index and the listing.
- Bid samples the same day. Sample clauses at bid close or within 7 days are covered on stocked parts.
- Line by line bid response. Send the schedule and get each line back with our part, the named brand cross, cut sheet and price.
- Submittal ready. Cut sheets, UL listing data and dimension sheets on request for every part.
- Program buying. Blanket POs, staged releases and FOB destination delivery, quoted to the terms in your RFQ.
- Trade terms. Net terms, case and project pricing, one contact for quotes, POs and tracking.
