Update: I contacted the vendor, and they sent the correct product (hollow core). Revised score to 4-star. (As a native Houstonian, I'm glad this Houston-based company had such good customer service.) However, beware of the 1/2" product.

Very disappointed. The product was not as described/shown. First, the listing shows a hollow-core wedge-shaped gasket. The hollow core is important, as it allows the gasket to compress and fit tightly. What was delivered (see photo) was a solid slab of rubber, completely incompressible. Second, the description was for a 1/2" width. The solid rubber was 1/2" but with the centralizer ribs, the overall width was 5/8". The gap I bought this for was exactly 1/2" in width. I had to shave off the ribs w/ a utility knife, and even then, driving a solid slab of rubber into the gap was not possible. I hammered on it w/ a mallet and 1x10 board, but it was a complete waste of $50.

You definitely need to buy the sample kit after using kit I ordered 30 feet of gasket and fit well and looks great. Great product!!

It is a great fit and give a good finish. Love this product.

Just placed the product. Can't say enough about it! Had previously used rubber caulk, had to use 16 cans at $8.00 each for a 4' space. All I did with this is clean out the gap (I used a screw driver) then placed one end in and pushed it down with my foot. That was all!!! So impressed. I ordered more for the rest of the rotted expansion gaps. Was hesitant at first but definitely recommend this for anyone wanting ease of installation and good price. Please make sure to measure your space before ordering.

The product is exactly as shown. It
Is easy to install and looks so much better! The product ships quickly.
