NiSi 112214 72mm Filter Stack Caps - Metal Protection

The NiSi 112214 Metal Stack Caps provide a practical storage and transport solution for photographers who carry multiple 72mm circular filters. Rather than packing each filter in its own case, you can screw your filters together into a single stack and cap both ends with these machined aluminum discs. The result is a compact, protected bundle that slips easily into a filter wallet or bag pocket.

The caps are made from aluminum, giving them a clear durability advantage over the plastic caps that typically ship with individual filters. Standard 72mm threading ensures compatibility across brands — NiSi, Hoya, B+W, Tiffen, and others all use the same thread pitch. Each cap threads on and off smoothly, and because it contacts only the filter's metal ring, there is no risk of scratching the glass. For landscape, portrait, and travel photographers who rely on ND, polarizer, or graduated filters, these stack caps add a small but meaningful layer of organization and protection to the kit.
