I need few of those quick tilt, single. Want to know if is the same as code s140-8 and 9

It appears you have our 15-175 Pivot Shoe. This uses our Series 152 Coil Balances. For a spring stamped '8', use the S152-8 8 pound spring; unfortunately, for other coil, there's really no way to say if it's stamped 6 or 9! This is a very annoying and common problem with replacing coil balances. Your best bet may be to obtain the exact weight of the window sash. Give us that exact weight, and I can work it out for you. 

Most Coil Balance systems are modular, meaning that parts are replaced individually. So one has to identify the springs they need, along with the shoe and housing. The 15-175 is the new shoe you need. For the housing around the coil springs, you can use our 15-143, 15-144 and 15-145 components that 'sandwich' around each individual coil. Again, I recommend weighing the sash so I can tell you the precise spring weights you need with the coils.
