Product Description

Gray foam backer rod — a flexible, compressible polyethylene foam “rope” used as a backing (bond‑breaker) behind sealants and caulking to control sealant depth, reduce caulk use, and allow joints to move. These products are commonly closed‑cell for water resistance and are sold as individual rolls in nominal diameters (3/8" is a common size) and multiple roll lengths (examples: 50 ft and 100 ft). Use as a press‑in filler for window/door, joint, pavement or general gap sealing; verify the exact diameter and length for your listing and confirm the provided SKU/barcode (079843001567) with the supplier before relisting.
