another very reliable source for cable and connectors/parts

I strongly suggest you all check out Anixter Wire and Cable. They are the largest distributor in the world for all types of wire, cable, digital interconnects etc. They have multiple stocking warehouses all over the country. Quantity on hand is almost never an issue.

Both. B&M and on line. I have been ordering massive quantities of all kinds of cable from mic cable to 750 MCM for years. They will ship or you can will call from any local office.

We design and install systems all over the country and we don't want to pay excess shipping costs for commodities like cable. That is why we buy primarily from Anixter as we can order it from any where in the country and have it delivered or PU from any other office.

We also use Graybar Electric for the same reason. They carry basic electrical install hardware as well as data and communication paraphenalia.

We also handle large venue portable installs such as conferences and conventions where we may need miles of cables of all kinds- mic, speaker, CAT5, coax, control etc.
