Do you use a pull down ladder to get into your attic? It is a fairly common way to access the attic, since it saves a lot of space, and it isn’t that much of an inconvenience unless you spend a lot of time in the attic. It is important to remember, however, that it is not a permanent installation, and as such, it is not as stable as a stair, or even a regular ladder. Usually, you will have at least one set of hinges on the ladder, and this will be a weak spot. If you are moving something heavy into your attic, it might be better to make a few trips instead of taking everything at once. You could also have someone hand you the items so you don’t have to climb the ladder with the heavy items. The ladder needs to be securely installed, since it could rip out of the frame and cause serious damage.
