Thank you,

unfortunately same result I’ve been getting up and down the internet and at all our local supply houses “out of stock” / back order … Schneider's dealer portal shows a deep negative qty about 6 months out. Hoping a fellow electrician maybe has one in the shop even used … the customer will pay up for it of course lol

A SQD distributor should be able to look up in their system to see if any distributor has these.

Good luck. I had an eBay saved search for that same part back from March and finally got one this month.
