In an effort to make life easier for our dealers, we've got a handy section of generic SKU's, placeholders, and wire-by-the-foot items in the catalog. To get to the generic section, search "zzz" in the catalog search bar.
From this page, you can then add more search terms, like Cat5, or use the filters on the left to narrow down results. This section has different wire types as well as SKUs for generic TVs, customer-owned hardware, etc. When added to a proposal, the items in this section will appear alongside the other products and can be edited the same way.
You can also create a Custom Item in your proposal.
