Threaded Adapters

We can make threaded adapters for numerous applications. We have extensive familiarity with matching threads and meeting tolerances that exceed loose international standards. Matching and adapting Metric or English threads in sizes from 20mm up to 200mm diameter is no problem. We can also create adapters and brackets to meet specific requirements with highly finished appeal.

Step Up Adapters

A “Step Up” Ring allows a larger sized filter to fit a smaller sized lens. Step up rings can be made with a knurled front edge to make removal easier. We can match some of the most unique and non-standard threads for these adapters. In those non-standard cases we will need the mating pieces on hand to guarantee the perfect fit.

Step Down Adapters

A “Step Down” ring ( “A” with shoulder) or bushing ( “B” no shoulder) allows a smaller sized filter to fit a larger sized lens. These are not commonly stocked by dealers because of the risk of vignetting. They are sometimes suitable for certain applications.

But threaded rings is just the beginning.

Threaded adapters aren’t just rings. They are unique pieces that meet an inspired vision. Manufactures make proprietary piece for their systems, but they only have eyes for their own equipment and they only make so many units each time. Our adapters join old or new equipment to expand beyond the imagination of the original designers. Bring us an idea and we’ll figure out what’s possible. For more capabilities and examples not including threads you can check our custom fabrication page. We also have a thread measurement page to help you determine what threads you have:
