Pre order height questions for Reef Octopus Super Space Saving Protein skimmers

I am about to order one of the Reef Octopus Super Space Saving Skimmers, I am looking at the SSS-5000INT and the SSS-6000INT. I am dealing with a height restriction so I want to ask about the exact dimensions so I can figure out if an internal skimmer is going to work for me. I am collecting data from several different websites. I am assuming I can trust the exact dimensions on the reef octopus website. So if the SSS-5000INT is 24" high, on the bulkreefsupply site it states that I would only need 1/2 inch clearance to be able to remove the collection cup from the skimmer, also it states the same for the SSS-6000INT which is listed at 24.4 inches high.

Am I correct in assuming that as long as I have 24.5 inches of space for the SSS-5000INT or 25 inches of space for the SSS-6000 INT, I will be able to remove the collection cup without any issues?

Thank you, Jeremy
