Customer Reviews for M-D Building Products 20 ft. Gray Foam Backer Rod for Large Gaps and Joints

It did the job

I am using this on the edges of some Viking shields, that will be wrapped in cloth, to soften them. Safety first!

I recently learned about this product while exploring how to fill in concrete joints. The product is reasonably priced, durable and easy to use. I plan on filling in more joints as I water proof and repair concrete joints for safety and a great look when complete. Thanks for this product design.

Good product that has a variety of different uses. My main use for it is when I have to caulk a rather large gap. I'll first fill the gap with backer rod, then caulk. I get better much results that way. It gives the caulk something to grab to, and the caulk won't shrink too much.

This product did what it said it should do. Good product for filling gaps.

Tired of having to review everything you buy. IT WORKED! What else do you need to know?

Great material to have on hand especially when encountering gaps of varying widths when replacing older windows with new replacement windows. It is easy and pliable to use and very versatile. I highly recommend purchasing it before any job that requires Gap filling.

Used this as a space keeper for a sliding door while running some cables, worked as intended.

Good products, easy to use and not an expensive price from HD. Thank you

I got this product to fill gaps in the bathrooms (under the sink, below the baseboards) and gaps in the microwave to keep roaches from entering. It does the job.

It worked great at sealing up around the window air conditioner

Easy to use and fills the gap perfectly. Cut the amount of sealant caulk need by at least half. Excellent price

I really like this soft foam for many different applications. Have been using this around some windows and doors in my pole barn and when I was installing flooring in our 100+ year old house. Very easy to cut and trim. Holds the position that I push it into without popping out. The fact that it’s soft and easy to work with makes it even better!
