This is an upgraded mesh organizer for the Pelican 1510 case. This lid organizer is night and day better than the org. 1519 Pelican version. This comes with stronger mesh material and lager/stronger pull tabs. This will hold up to wear and tear. This lid organizer allows you to maximize the space in your 1510. Perfect compliment to your divider set, foam set, TrekPak insert, or to your empty case. This is made by CVPKG(ColorCase). This is not made by Pelican. Approx. dims - 19.50" x 10.75"
