30" Five-Tread Stairs

This 5-tread stairstep adjusts to different depths as easily as our sections do, with two cam mechanisms. But there’s a bonus, you can vary the angle too. Make the steps vertical if you want, or almost horizontal. Two simple hand knobs secure the stairstep firmly to the dock

If you keep your dock higher off the water because of large waves or because you’re afraid of water (which doesn’t really make much sense because why would you buy steps), then seven treads are for you.
