Review on Nelson CSH16 42 10 24: High-Performance Industrial Tool for Efficiency and Precision by Jason Vigil

I was very impressed with these seals. They were of very uniform thickness and quality, with no knots or other defects. I used them to level my hot tub on a sloping deck. The extra 16 inches of length and the fact that they are cedar made them the perfect choice and they worked great! Very satisfied and would buy again.
