M-D backer rod is a non-absorbent, closed-cell polyethylene pre-caulking material used to fill wide gaps and joints before applying caulk, helping caulk perform correctly in oversized openings.
- 5/8 in. diameter x 20 ft. length
- Use for gaps and openings larger than 1/2 in. x 1/2 in.
- Prevents three-point bonding so caulk can flex properly
- Gray closed-cell polyethylene resists moisture absorption
- Compatible with most standard caulk types
