For the caps side base rails (when using a Front Rail Seal) install one of ESIs high quality 20ft truck cap seals (see choices below). To seal the caps front and side base rails (not using a Front Rail Seal) install one of the following 20ft or 23ft length truck cap seals: 1 1/2" wide Super Cap Seal 23ft (ASIN: B00C7VU9BA) or Super Cap Seal 20ft (ASIN: B00NCC0SY6) fills all bed rail gaps, use on truck caps that weigh 200 lbs or less. 2" wide Premium Cap Seal XL 23ft (ASIN: B00IPQR63A) or Premium Cap Seal XL 20ft (ASIN: B00NCCX6C2) fills small to medium bed rail gaps, use on truck caps that weigh 200 lbs or less. 2 1/8" wide Super Cap Seal XL 23ft (ASIN: B00BNGBXOC) or Super Cap Seal XL 20ft (ASIN: B00NCCNUJQ) for trucks with extra wide bed rails, fills all bed rail gaps and for caps over 200 lbs. 1 1/2" wide Ultra Cap Seal 23ft (ASIN: B00MPMBIZW) or Ultra Cap Seal 20ft (ASIN: B00NCCDXJ8) fills all bed rail gaps, for caps over 200 lbs.
