NiSi 82mm Metal Stack Caps

The threaded design makes stacking filters feel rock-solid and secure, not wobbly like other caps I’ve tried. Having both top and bottom covers means I can leave my filters stacked and ready to shoot.

These stack caps fit so precisely that I can just leave them on my filter stack in my bag without worrying about scratches. The threading is smooth and catches immediately, which is exactly what I needed for protecting my 82mm filters.

Finally, a cap set that actually screws on smoothly without cross-threading. The metal threading feels much more secure than the plastic ones I've used before, and it keeps my filter stack perfectly snug.
