Simply screw your filters together then screw the stack caps on the top and bottom.
The NiSi 82mm Metal Stack Caps can be used with a minimum of 1 x 82mm filter and can be used to protect 20+ 82mm filters screwed together.
The metal construction offers protection to filter surfaces and protects the filters from dust, scratches and fingerprints while not in use.
