Greetings UKNOF folks... I'm after some of those lightweight "corrugated cardboard" (can't think of what else to call them) blanking sheets to put in racks to stop hot/cold aisle "rebreathing". Want to give these a go, but keep coming up on metal blanking plates. Anyone got a manufacturer/suppli

I have used these at $previous job for a 400 rack site and they worked out well. We found many of the other types to leak air and need clips that run off to never be found again. These just clip in, no seperate parts. http://www.ebuyer.com/188594-apc-modular-toolless-rack-blanking-panel-black-1u-

The data-centre I was in yesterday used the plastic ones from CannonTech and they looked very up to the job. Am I the only person on here that thinks all the current blanking solutions are very expensive for what you get? After all its just a piece of fire-proof plastic? Jon Dixon On 28/04
