Combo vs 2-in-1 RV Slide Out Seal: Which 018-312-EKD & 018-341 EK Kit Should You Buy?
Both combo kits pair the 018-312-EKD D seal with the 018-341 EK base seal in black, and both follow the same easy-install steps. The difference is $22, so the Combo RV Slide Out Seal at $63.99 is the better buy unless you need the 2-in-1 title wording.
