Attwood 11401-4 Pontoon Storage Blocks, Set of 4

The Attwood 11401-4 Pontoon Storage Blocks are a set of four plastic support blocks built to hold a pontoon boat off the ground during winter storage or off-season layup. Each block uses a lift-off lid opening mechanism and an adjustable design, letting the set accommodate different pontoon tube diameters and boat weights without needing custom-fit hardware. The blocks are molded from durable plastic and finished in black, and the set is intended for storage use, cradling the pontoon tubes to keep them off wet ground, away from standing water, ice, and uneven surfaces that can deform or damage the tubes over time.

This is a universal-fit product, meaning the set is not restricted to a single pontoon boat make or model and works across a range of pontoon tube sizes. The set of 4 blocks ships together as a complete kit, with no additional hardware required for basic setup. Attwood is a long-established manufacturer of boating accessories and storage solutions, and the 11401-4 storage block set is sold as part number 11401-4.
