I have replaced our S2208 with the AH2510 but only gained an inch in the opening. Since the S2208 had a metal frame and AH2510 has a wooden frame, the gain in the actual opening was minimal not the 22.5" to a 25" opening as expected. We removed 2 2"x4" in the sides of the attic opening for a total of 4" to meet the 25" width requirement and expected to get more than 1" additional width into the attic.
The actual outside frame of the AH2510 is only 24.5 " and the inside opening to the attic is 23" when installed and then the braces take away a little more of the opening. It would have been great to have the frame actually be the 25"...instead I have .5" gaps on the side of the frame which I would have preferred to be a wider opening into the attic
As part of the specifications , Werner should include the the actual opening (inside of frame) size.....the main reason to upgrade to the 25" ladder was to get a water heater into the attic, so inside frame size is everything. With the packaging..."Extra Wide" 25x 54" Opening size is misleading.
I realize that you only purchased the Werner name and not the products, but going forward how will I be aware of any issues with my current ladder as I do not see a place to register my ladder?????
Just out of curiosity, why is the Energy seal ladder only available in the 22.5"? You should insulate all of the doors.
