Bridging Packers?

[NewShoes]

Hi, I'm about to order some new sealed units to replace misted up ones. I know the dimensions etc but, on watching a couple of YouTube videos on how to correctly fit the new panes, I see there is something called a bridging packer. These seem to different to the usual coloured plastic glazing packers in that I think they allow water to run underneath them whereas the usual packers wouldn't as the have a type of grid formation on the underside. Does this sound right and, if so, where would you usually get these bridging packers as I can't seem to find any.

Cheers

Thanks, I'm guessing I need a specific one to fit my particular profile? Would it be safe to assume that as I'm replacing panes that a bridging packer(s) might already be in place or are these normally not bothered with?

It all depends who fit them and what they chose to use, you may have some in or you may not but they are easy to cut to width to suit the frame channel.
