M-B Sprinter W907 cargo rubber floor mat (cut to shape). Fits to 6/2018 and newer cars. Available in medium, long and extra long models. The rubber mat significantly reduces sliding of the objects. You'll also keep your car tidy for much longer. The carpet has cut-outs for the tie-downs. Choose the length of your car from the pull-down menu when ordering.
The mats are cut to shape for cars with a sliding door on the co-driver's side. If your car has a sliding door on both sides, you can use the same carpet but you have to cut the shape of the opening on the left sliding door by yourself.
