FEATURES - All ladders are made of high quality 6063 marine grade aluminum, and TIG welded for superior strength and rigidity. - Ideal for use as a safety ladder. Some municipalities require a safety ladder for every 50' of dock. - Ladder rung is notched into vertical side rail for added safety. In the unlikely event of a weld failing, the ladder rungs are still fully captured. - Grooved ladder rungs allow for extra traction and water run-off. - 3 & 4 step ladders can be sent FedEx Ground. 5, 6, & 7 step ladders are sent freight. - Shipping ladders have removable handles for shipping via FedEx Ground. 3 thru 7 step ladders can be shipped this way. - Each step will equal approximately 1 foot down from the top on the mounting surface (i.e. 5 step ladder = 5' down from deck). - Custom designs, widths, and lengths available upon request.
