There are four aluminum thumbscrews used to attach the Super Chromega D Dichroic colorhead to the lifting arm assembly on Omega D-5, D-2, D-6, D-3 and D-4 enlargers. If your colorhead is missing one or more of those screws, this is the proper replacement. Screws for mounting the condenser lamphouse are also available - please see the separate listings. The screws are new, sold individually, supplied in plastic pouch. |
