Cable Clamp

Can a cable clamp such as the one showed by Stillwantmore be purchased at a local or hardware store like Home Depot or Lowe’s?

I bought mine at Home Depot. They were sitting in a freestanding bin, but I don’t which section exactly. If you search for the original thread I’m sure myself and others give more information.

Wal-Mart sells them in 2 types of packages ( I think in the electrical dept ):

1. 2 medium sized ones and 2 small ones.

2. 1 large, 1 medium, and 1 small.
