This unique ladder with fold-out steps stores within the hull and when it's not in use, just a clean 5" x 4.5" quick access transom plate is visible. The anodized aluminum 2" square channel body deploys out at a 15 angle and mounts 4" above the waterline. Requires a 13 angled transom, a 3" hole, and a 35" tube (included) inside the boat for ladder storage. Once installed, just slide out the ladder, fold out the steps and it's ready to go. Made in the USA.
