AL-B4 Compact Aluminum Four-Step Pontoon Boat Ladder

 Back to: Marine Parts

When you want the best, you go to the best. That’s why you’re here at looking for a top-of-the-line slim profile ladder for your pontoon boat. Look no further than our AL-B4 Compact Aluminum Four-Step Pontoon Boat Ladder. Our most compact boat ladder, the AL-B4 has a flush mount design and mounts easily to your water craft*

While other pontoon ladders are clunky and create tripping hazards on your boat (which is the last thing you need when you’re relaxing on the lake with a few of your favorite frosty beverages) this ladder has no raised brackets for your feet to get caught up on. Because of its slim design, this ladder is stored easily when not in use. If you really want to maximize your space, purchase the extra mounting clips to put this ladder on your railing and out of your way!

Built to withstand the elements, this ladder is constructed with long-lasting aluminum tubing. The 1” round bars will stand the test of time through multiple uses in the harsh marine environment. The entire ladder is anodized for extra protection during your nautical excursions. The steps of the ladder are made of an extra durable marine grade plastic designed just for the rigors of water environments.
