Overview

The Attwood Marine 912818 is a non-threaded locking collar for compatible Attwood all-round lights. It is a small replacement part, but it matters when the light pole needs to seat and lock the way it should instead of working loose in normal boat use.

This collar is black and made for the non-threaded style used on certain Attwood light assemblies. It fits best when you are repairing an existing navigation light setup and need the correct collar rather than a complete light or base.

Key features

• Replacement locking collar for compatible Attwood all-round light assemblies
• Non-threaded design for setups that use this collar style
• Black finish that blends in with common navigation light hardware
• Useful when the original collar is worn, missing, or no longer holds the light assembly as securely as it should

Compatibility and fit

Fit is the main thing to check with this part. This collar is for the non-threaded version, so it should be matched to an existing Attwood all-round light setup that uses the same style. If your current assembly uses a threaded collar or a different base arrangement, this is not the correct replacement.

This kind of service part is most useful on boats where the all-round light is removed for storage, handled often, or exposed to vibration underway. Replacing a worn collar can help restore a more secure hold at the light connection point.

Installation and setup

Installation is straightforward when it is being fitted to the matching light assembly. Compare the old collar to the replacement before install, then check that the light pole locks in cleanly without forcing parts together. Because this is a collar only, it is intended as a replacement part within an existing navigation light setup.
