If the original bellows on your Omega D-5 or D-6 enlarger has been damaged or is in otherwise poor condition, this is the proper replacement. The bellows are supplied pre-assembled, with the bellows material attached to the metal frames at the top and bottom of the bellows, ready to install on the enlarger and supplied with 8 new mounting screws.
The used bellows assemblies have been cleaned, carefully inspected, and are certified to be in perfect working condition. They are also supplied with new mounting screws.
