Looking for a 16 outlet metal power strip with widely-spaced outlets suitable for transformers.

Only one such product on Amazon is UL-listed (Tripp-Lite PS4816/PS4816B) and the outlets on it are oriented badly for transformers.

It's unreasonable to be selling high voltage products that aren't UL-listed, but Amazon is happy to sell all manner of unsafe Chinese products with no checks and balances. Somebody's house is gonna burn down and the insurance company is going to deny any claims.
