## Questions & Answers

**Q: Does this work on 12 inch siding**
A: No, neither the SA902 nor SA903 work on 12" siding. There is a model SA902.12 that is made specifically for use on the 12". It is basically the model SA902 with a pair of long aluminum extensions included in the package. Since this model is made of aluminum it isn't recommended for use on the pre-finished siding as the aluminum tends to leave marks.

**Q: What makes this zone 10 specific?**
A: http://www.jameshardie.com/dealer/hardiezone.shtml + http://www.jameshardie.com/homeowner/hardiezone-video.htmlThe Zone 1 - 5 product has a specific drip edge design and since this tool clamps at that edge, you use it on zone 6 - 10 products.

**Q: Would these work installing the big 0.312-in x 48-in x 96-in hardiepanel vertical fiber cement siding panels?**
A: These are for panel siding … clamps to Z Flashing to hold up the panel.  https://www.amazon.com/dp/B001PBJ6QM?tag=price125420e-20&ascsubtag=wtbs_60358245085322c828fd7606
