Claims19
A threaded insert for an airfield light fixture comprising:
- a top end and a bottom end;
- a cylindrical wall running between the top and bottom ends of the threaded insert;
- a lip integral with the cylindrical wall proximate the bottom end of the threaded insert, wherein the lip has a diameter greater than the diameter of the cylindrical wall;
- an opening proximate the top end of the threaded insert and extending throughout the cylindrical wall to form a cavity between the interior of the cylindrical wall and the lip;
- a plurality of protrusions extending radially from the exterior of the cylindrical wall;
- and
- a tapered portion proximate the end of the cylindrical wall opposite the lip, wherein the cavity extending throughout the cylindrical wall and tapered portion has a substantially uniform radius and the exterior of the tapered portion forms an angle with the plane of the cylindrical wall;
- and
- wherein the interior of the cylindrical wall is threaded.
