The attachment that JAMMFAM listed from Camping World is the exact one I purchased for my bunks. I went to Home Depot and obtained a couple straps and a piece of hardwood where I designed & constructed a landing for the hardware that came with the ladder. I stained the wood the same color as the bunks were and cut the legs of the ladder (easy job because it is aluminum) so it would stand straight up, saving space in the bunkroom. Works perfect, looks good and keeps the grandkids from performing acrobatics to reach the upper tier of bunks.
