An elastic roof rack net with scalability could stretch from About 36" x 48" to About 72" x 96". The net is made of a thick cord, it is strong and durable (also used for bungee jumps). It is designed to tie down and strengthen small items from slipping out providing extra strength and protection when stretched over larger items.
The roof rack net comes with 12 removable ABS plastic hooks that can be moved from one grid to another for quick tightening adjustments, for managing and organizing loose, bulky, or awkwardly shaped cargo.
Manual net knot design makes it much more durable than the plastic knot, able to bear more heavy cargo.
