An aircraft comprising:

• a seat track;
• and
• a track filler installed in the seat track, the track filler comprising:
• an elongated body comprising:
• a first sidewall having a first top end and a first bottom end, and formed along a first side of the body;
• a second sidewall having a second top end and a second bottom end, and formed along a second side of the body, opposite the first sidewall;
• and
• a topwall joining the first top end and the second top end, wherein the body forms at least a partially hollow interior portion;
• a plurality of periodic notches along the first bottom end of the first sidewall and the second bottom end of the second sidewall and extending toward the first top end and the second top end, respectively;
• a plurality of periodic grooves extending partially through the topwall, wherein each of the grooves extend from a notch at the first top end to a corresponding notch at the second top end;
• and
• a plurality of support members attached to the topwall and at least one of the first sidewall or the second sidewall along the interior portion of the body.

• a plurality of periodic notches along the first bottom end of the first sidewall and the second bottom end of the second sidewall and extending toward the first top end and the second top end, respectively;
• a plurality of periodic grooves extending partially through the topwall, wherein each of the grooves extend from a notch at the first top end to a corresponding notch at the second top end;
• a plurality of support members attached to the topwall and at least one of the first sidewall or the second sidewall along the interior portion of the body;
• wherein the elongated body is configured to be shortened to one of a plurality of predetermined lengths by breaking the elongated body along one of the grooves;
• wherein the elongated body comprises a first elongated body portion and a second elongated body portion, wherein the first elongated body portion is the shortened elongated body insertable in a track;
• and further comprising an adapter positioned at least partially within the interior portion of the body to couple the first elongated body portion with the second elongated body portion, the adapter comprising a gripping member configured to prevent the track filler from sliding against a track when the track filler is installed in the track.
