Basically followed the guide. I attached the outside blocks the the ladder box, then framed the opening to the overall size. The ladder box dropped in place perfectly. Only problem came after reinstalling the stairs. With the stairs mounted in the topmost hole then wouldn’t clear the box frame so I dropped them down to the middle point and all is well.they are a bit long so some trimming to the bottom section is in order. Overall very pleased.
FIRST TIME INSTALLING THIS PRODUCT FOR A CUSTOMER. LADDER IS WELL BUILT AND MUCH NICER THAN PRODUCTS I HAVE USED IN THE PAST. WILL DEFINITELY PURCHASE AGAIN FOR NEXT ATTIC LADDER JOB.
