Flanges and Retainers for Photographic Shutters and Lenses

Flanges & Retainers

I can routinely supply missing lens retainers and mounting flanges.
Large stock of finished USA and Metric mounting rings.

A mounting flange is a metal threaded ring with several holes bored into it which is used to allow a shutter or lens to be installed onto a lensboard. It is permanently attached to the front of a lensboard with screws. Flanges are frequently missing from their lenses. If you have extra flanges, you can fit them to several different lensboards and can then easily switch a lens amongst different cameras.

A retainer is similar to a flange except that it has no holes bored into it and is used like a "nut" in a "nut and bolt"; it holds the lens or shutter onto the board more or less permanently by screwing on from the back. Retainers often require a special tool to install or remove, so lenses mounted with them are not as easily interchanged as those using flanges.

Prices range from $10.00 - $15.00 for small factory made retainers. Custom flanges from $75.00 for small flanges, to $95.00 for medium size flanges, and up to $140.00 for large size mounting flanges. Dealer pricing as low as $15.00-20.00 per ring in mixed assortments as few as two dozen rings. Call and chat me up.

Getting Them To Fit
The best way for you to ensure the fit of a specially made ring is to send me the lens that will used with the ring, so that I can guarantee it's fit. The next best way is to measure and specify the existing thread.
