Shipping Note:
Ladders are one of the most interesting products we ship. The vast majority of ladders will ship via truck freight because of the size and/or weight. We try to use the best and least expensive carrier whenever possible, however carriers can vary by as much as $100 for an identical shipment. Because of this, it is not possible to provide a shipping price at check-out.
You may complete your order online, however there will be no shipping charges displayed at checkout. Please provide an accurate shipping address at check-out, and a First Out Rescue specialist will contact you to make delivery arrangements and give you the final cost for your order including freight charges.
Delivery Times:
March 2025 - We have been advised by Duo-Safety that delivery times on all Duo-Safety ladders is 1 year (365 days). You may want to consider Alco-Lite Fire Service Ladders instead.
