    ### Nairn 4 inch Inspection Port Lid Only Black

Replace a missing or damaged lid on a matching Nairn 4-inch inspection port with this black ABS plastic spare. The lid-only format lets you retain an existing rim when that rim is still suitable for service.

Code 404650 is the black version for the 4-inch Nairn family. Confirm the make and nominal size of the installed port, then compare the lid engagement with the existing rim. Matching colour alone does not establish fit.

Inspect the rim and O-ring as part of the replacement. This listing is for the lid, so a complete port assembly or replacement seal should be selected separately when those components also need attention.

### Choosing and using this product

Consider how the fitting will be used in the normal boat layout. Allow room for hands, tools and any intended movement, and check that it does not obstruct an access opening or another control. Offer the parts into position before marking or making permanent changes.

Include the attachment points in routine boat inspections. Keep moving or seating surfaces clear where applicable, and follow the product’s care instructions for its material and finish. Retaining the size and part code is useful when replacing another fitting elsewhere on the boat.

The listed material, finish and dimensions help you select a version that suits the job and surrounding fittings. Measure the actual location rather than relying on a familiar-looking shape. Small differences in projection or spacing can change how comfortably the completed arrangement works.

Check the stated supply quantity and inclusions when ordering. Some listings describe an individual component, while others supply a pair, pack or complete assembly. Match any additional fixings and supporting parts to the installation requirements rather than assuming they accompany the visible fitting.
