At Gerry’s Fishing, we find the Sonik Smartstack Storage Box (Small) to be the ultimate solution for the organized angler who needs a compact, high-protection “bits” station. With a 16-litre capacity, this model is the smallest in the modular Smartstack family. It is specifically designed to store essential terminal tackle pouches, bait tubs, or cooking supplies while taking up minimal space on a barrow or in your vehicle.
Built from heavy-duty, weatherproof plastic, the Small Smartstack is designed to live in the toughest environments. Whether it’s sitting in a damp boat or on a muddy bank, your gear inside remains dry and clean. Its most useful feature is its stackable modularity, allowing it to lock perfectly into the lids of other boxes in the range, creating a stable, vertical storage system that won’t topple over.
The Small Smartstack is a precision-sized storage unit built for the mobile angler:
| Feature | Specification |
| Model | Sonik Smartstack Storage Box – Small |
| Capacity | 16 Litres |
| External Dimensions | 40cm (L) x 30cm (W) x 21cm (H) |
| Material | High-Impact, Weatherproof Plastic |
| Stacking System | Interlocking Bases & Recessed Lids |
| Handles | Side Clips with Integrated Carry Function |
| Height Category | Low-Profile (Fits Underbed) |
Interlocking Modular Design: The base of the Small box is engineered to fit into the recessed lids of the Medium and Large models. This allows you to build a custom “tower” of gear that stays together during bumpy barrow trips or boat transits.
Underbed Profile (21cm): Just like the Medium version, the Small box has a height of 21cm. This is the optimal dimension to slide under the vast majority of carp bedchairs, keeping your bivvy floor clear and your essentials within arm’s reach while you sleep.
Weatherproof Protection: The robust plastic construction is moisture and dirt resistant. It acts as a primary defense for sensitive items like spare headtorches, power banks, or expensive bait that needs to stay away from the damp.
Dual-Function Side Clips: The heavy-duty clips serve two purposes: they ensure a tight, secure lid seal and are shaped to act as carry handles for easy lifting.
Tough Utility Handle: Even when fully loaded with heavy leads or liquids, the reinforced plastic ensures the box won’t flex or crack under the weight.
Space-Saving Footprint: At 40cm x 30cm, it is compact enough to fit into the corner of a boot or side-pocket of a large barrow, making it the perfect choice for short-session or roving anglers.
You can combine the Small box with its larger siblings for a perfectly organized bankside experience:
Small (16L): 40cm x 30cm x 21cm – Best for end tackle, leads, and small pouches.
Medium (36L): 60cm x 40cm x 21cm – Best for clothing, food, and towels.
Large (66L): 60cm x 40cm x 36cm – Best for bulky winter gear, boots, or bulk bait.
Gerry’s Pro Tip: The Small Smartstack is the perfect size to act as a “Lead & Tool Station.” Because it is so robust, it can handle the weight of 10kg+ of lead weights without damaging the box. Keep your leads in the bottom and your rig tools in a pouch on top; you’ll have everything you need to rebuild a rig in one indestructible, weatherproof container.
