Overall winner: 1/2 in x 200 ft foam backer rod for gaps and joints

Key Differences

Product A (1/2 in x 200 ft) offers four times the length of Product B and a narrower 1/2 in diameter that fits smaller gaps; Product B (1 in x 50 ft) provides a larger 1 in diameter better for wider joints but only 50 ft of material. Choose A if you need long runs and narrower backer rod; choose B if you need a thicker diameter for wider gaps in shorter runs
