Topper Mast Collar

The genuine Topper® D11 Mast Collar is designed for Topper lower masts using the updated gooseneck system introduced after March 2014.

The collar fits around the lower mast and provides the correct bearing surface for the newer-style Topper gooseneck. It is suitable for replacing a worn or damaged collar or upgrading an older lower mast to the post-2014 gooseneck arrangement.
