| This is the square upper bellows on Beseler 4x5 enlargers, including the 45M, 45MX, 45MCRX, 45MXII, 45MXT, and 45V-XL, that fits between the upper negative stage plate and condenser support stage, and allows you to adjust the position of the condensers for different negative formats. If the upper bellows on your Beseler 4x5 enlarger is torn, cracked, worn, or otherwise leaking light, this is the correct replacement. Replacement lower bellows are also available - please see the separate listings. |
