Are you thinking of Cokin?
Their Creative Filter System consists (from the lens out); Screw in adaptor ring or universal ring for non standard threads. Slide filter holder into which square or round filters slide as well as a modular lens hood. One may also attach a second filter holder to it.
The system comes in two sizes; A 36 t0 62 mm diameters and P 48 to 82 mm diameters.
There are a number of other accessories and adaptors and an army of filters and special effects devices.
It has been a long time since I bought mine so there may very well be many more fittings for the system.
You can probably get complete, detailed information if you Google Cokin.
