If your truck has a non-standard tailgate or one of the excluded designs, review ESI's XL, UTV or trailer variants or consult product fit guides before buying.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the 4.25\" ROK BLOCK fit all trucks?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It fits most pickups at 64\" length, but some models need the XL 7\" version or are excluded; check fitment before buying.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How do I install the ROK BLOCK adhesive?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Apply between 50°–104°F, press with about 25 lbs. force, and use 3M ST1200 tape for best adhesion.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"ESI","offers":[{"title":"Default Title","offer_id":67587278733497,"sku":"B00BPE4AP6","price":95.31,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/3765\/3177\/files\/esi-rok-block-front-installed.jpg?v=1790503928","url":"https:\/\/redleafauto.ca\/products\/esi-rok-block-64-tailgate-gap-cover-4-25-universal-pickup-seal-3m-adhesive-reduces-debris","provider":"Redleaf Auto","version":"1.0","type":"link"}
