Is your Beseler colorhead looking a bit shabby because one or more of the color discs have fallen off the knobs and been lost? Replacement discs have never been available from Beseler, only the entire knob. We can now offer a set of durable plastic cyan, magenta and yellow replacement discs. They're self-adhesive so you just peel off the backing paper and press them in place.
Beseler has used knobs in several different sizes. These replacement discs are approximately 7/8" (22mm) in diameter to fit the larger size knobs on certain Beseler colorheads, such as the 23C Dual Dichro, and some Beseler color analyzers, such as the PM2. Smaller 3/4" (19mm) size discs are also available, please see the separate listing. Sold as a set of three.
