A few points to make sure you know. For pull down attic stairs both of the main manufacturers, Louisville and Warner clearly state that unless you use the PROPER fasteners that go into the bottom chord of the trusses it will void the warranty and is a serious safety hazard.

You MUST use either TEN 16 D common nails or TEN 3' Lag screws. The problem is that MANY gutter companies do not use these approved fasteners and they use long gutter screws instead. It is NOT correct. My company has confirmed this with both companies.

Also, made sure they face the correct way...towards the peak. We see too many installed the wrong direction and you hit your head on the sloping roof with the roof nails that stick out through the roof sheathing. Hope this helps!
