New 8-Inch Crack-Opener
This new stainless steal crack-opener fills the gap between the extreme crack-opener at 10-inches and the small 5-inch crack-opener. Price is $60.00
Size Does Matter
The larger the crack-opener the better. The physics of a larger opener gives you mechanical advantage and more leverage. Longer openers will open more of the crack and it will open it wider and more even. You will not see any spots with the 8 or 10 inch openers when you release the pressure. In fact you will see resin come out the top of the crack as it has slightly over filled while it was preyed open. You should always use the largest opener possible.
