As the original inventor and world’s largest manufacturer of welded wire mesh cable tray, Cablofil cable tray products have many unique and patented features. Cable tray manufacturers have traditionally used a common wire size throughout the entire tray. Through our research and design efforts, Cablofil has discovered that certain wires in the cable tray are load bearing and other wires are not load bearing. Our cable tray design takes this into account. The top longitudinal wire and the cross wires are 5.9mm. All other longitudinal wires are 3.9mm. This unique combination of wire sizes, patented in the United States and around the world, allows Cablofil cable trays to be stronger than the competitors that must use all 4mm diameter wires to achieve comparable load capacity. Please reference our load table on catalog page A.6

Cablofil recommends using stainless steel hardware with stainless steel wire mesh cable tray.

Cablofil recommends wire mesh cable tray be supported on 5'-8' spans.

Yes. This is a blind end with a black powder coat finish for Cablofil's 4" x 18" wire mesh tray.

Cable tray does not have voltage ratings. This tray rated cable can be installed in any cable tray.

The spacing between expansion splices is determined from the temperature differential and straight tray footage between bends. NEMA VE2/NEMA BI50016 standards publish a table used to determine this spacing. As an example, for a temperature differential of 25 degrees Fahrenheit, expansion splices should be used with wire mesh cable tray every 512 feet between bends. It is rare that expansion comes into play with wire mesh cable tray. For additional information, please reach out to Cablofil tech support at technical.support-CAB@legrand.us

I would say you are correct. On page 18 of the Legrand Installation Guide, shows 9 cuts are needed for a sweep 90 on an 18" wide cable tray.
