Purchase options and add-ons

  • HIGH QUALITY MATERIAL: This Caulk Backer Rod is made of high quality material that is long lasting, durable and weather resistant. Our product can effectively fill large gaps between surfaces to prevent drafts, insects, dust and pollen from entering your home.
  • CONCRETE GAP FILLING: Our product is an excellent choice for filling areas with concrete to ensure a sound surface for caulking projects. Use this rod to fill joints between two surfaces that allows caulking to securely hold in place and lasts longer.
  • WIDE RANGE OF USES: Whether you’re fixing a leaky roof, window sill or drafty door; the Caulk Backer Rod can handle the job! In addition to sealing gaps between surfaces, it’s also great for insulating and improving air tightness as well as damp proofing your home.
  • EASY TO USE: Installation is easy with a simple push into most joint openings until it's snugly fitted. After installation caulk can be applied on top of the backer rod for an extra secure seal without the use of messy sealants or adhesives.
