Four aluminum thumbscrews are used to attach the condenser lamphouse to the lifting arm assembly on Omega D-5, D-2, D-6, and D-3 enlargers. If your condenser lamphouse is missing one or more of those screws, this is the proper replacement. (If you require a full set of 4 replacement screws, we also offer a money saving set of four used thumbscrews - please refer to the separate listing.)
These screws are new, sold individually. Screws for mounting the Super Chromega D Dichroic colorhead are also available - please see the separate listing.
