The Premium ST Ladder® is truly the best dock ladder available today. Designed to feel more like stairs than a ladder, the DockinaBox® Designer Series Ladder have angled sides and are constructed using highly engineered extrusions and materials. With an anodized finish and using only stainless steel hardware, the Premium St Ladder will stand up to the test of time.

The tall curved top rails provide a smooth streamlined look that is as comfortable and appealing.

One of the most appealing features of the Premium ST Ladder® is the huge 12″ top step with molded, rubber traction, when folded down. The tall curved top rails provide a smooth streamlined look that is as comfortable and appealing and the patented folding steps puts two steps together making it great for sitting with your feet in the water. The Premium ST Ladder features a locking pin allowing the ladder to fold to a comfortable 20° angle, keeping the ladder steps out of the water and free from floating debris. The locking fold feature also makes for effortless and space saving winter storage.
