ProOPTIC 77mm Filter Stack Caps

The ProOPTIC Filter Stack Caps are designed for 77mm filters, providing a professional storage solution. The set includes one male and one female metal cap that screw together to form a protective case. This accessory suits photographers who need to keep filter glass clean and scratch-free in the studio or field. The precision threading ensures a secure fit without over-tightening.

Capacity and headroom: 77mm filter protection

These caps accommodate standard 77mm threaded filters, shielding the front and rear surfaces from dust, moisture and impact. The metal construction delivers robust protection during transport in a gear bag or while stacked on a shelf. The smooth threads allow quick access when a filter change is needed on location. The design does not accommodate filters with non-standard thread pitches or larger diameters.

Upgrades from basic plastic caps

This set replaces flimsy push-on caps or single-thread protectors that can loosen in a bag. The male-and-female pairing creates a sealed enclosure that prevents contaminants from reaching coated glass. The jump is worth it for shooters who carry multiple 77mm filters and need reliable, repeatable protection. It does not address storage for filter systems that use non-threaded mounts.

Highlights

  • Protects 77mm filters with durable metal construction
  • Includes male and female caps for secure fit
  • Smooth threading enables quick filter access
  • Stackable design prevents scratches and dust
  • Rugged build suits studio and field use

Questions about this item

Will the 77mm male cap thread onto the front of my 77mm filter?

Yes, the male cap screws directly onto the front 77mm thread of any standard filter.

How can I confirm the caps seal properly after I screw them together?

The metal threads engage smoothly and hold without binding; a gentle shake should produce no rattle when both caps are joined.

Does the package contain both the male and female 77mm caps, or must I buy one separately?

The set includes one male-threaded cap and one female-threaded cap — no additional purchase is needed.
