AI-generated summary
For £35.23 ex-VAT, the Allied Telesis AT-RKMT-J13 Grey Metal is the kind of small, unglamorous rack accessory that’s only “worth it” if you actually need that specific mounting solution in your cabinet. In real deployments, these parts save time and reduce the faff of bodging brackets or using the wrong hardware—so if you’re standardising installs across sites, it’s a cheap way to keep things looking consistent and stop annoying mechanical tweaks later.
That said, it’s not something I’d buy just because it’s from the same brand as your kit. If you’re not already aligned to the exact rack/cabinet fit and that J13 mounting requirement, you could end up with a perfectly priced paperweight. Best for IT teams doing repeat installs with Allied Telesis gear (or maintaining existing racks) where compatibility is already proven—less good for “let’s see if it works” builds. If you tell me what you’re mounting and which cabinet/rack model you’re using, I can sanity-check whether this is likely the right match.
