In case your search hasn't been successful, try looking up stainless steel fabricators or metal fabricators. Alternately you can search for companies that provide the hardware and see who either carries or places large orders locally. To clamp the wire ends, one needs special equipment to do it properly.

i believe in canada you must have vertical wires, not horizontal, too bad because i love this too

Thanks for the response "ucarchitect". I'll do just that:)

I got kits from GreenOxen and had my contractor install them. They look awesome!

Thank you for reaching out! While we do our best to retain
as much information as possible for each project, unfortunately we do not
always have all the details regarding materials/furnishings/sources/costs/etc.
Often, the builder or interior designer are a great source to provide more
specifics on these inquiries.
