Difference in AC shroud

[Barry J]

I am trying to buy a Duotherm AC shroud, but it list an open end or and closed end..what is the difference
I attached a pic

That appears to be an open end cover if the black potion is open or a grill. The closed is just that, a four solid sided box.

...don't know--perhaps Brisk-Air model vs Penguin II????? For the P-II to operate efficiently, it is absolutely essential for the foam gaskets UNDER the shroud [not the one under the unit] be replaced/re-aligned to match air flow so you keep the warm side warm and the cool side cool…...

My original was open, clear view of the coil. When I received the replacement it had fins on the back similar to the sides. I used a pair of tin snips and cut the back to be the same as my open style. I did this to make sure there was no air flow restriction interfering with the gas/liquid freon conversion.
