## 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

**Q: Will this work with 1in by 8in cedar bevel ?**
A: Probably not. It’s only for 5/16 siding

### ⭐⭐⭐⭐⭐ Outstanding tool!
*by T***N on August 27, 2010*

If you are considering installation of Hardie siding, this rather simple tool is a must have. Yes, they are not inexpensive considering their simplicity, however, you will experience a very significant savings in time and effort which more than offsets the $60 investment for the pair. You do need two for proper and accurate installation of siding. Very fast,easy to use, accurate, and durable unless dropped onto a very hard surface like concrete. The body is made of a tough plastic but it will crack if mistreated. Don't let this happen and you can use them for a very long time. Not much to wear out really. We did drop one off a ladder from about 15 ft onto a concrete pad. The body cracked on a diagonal approx in the middle of the tool. Using Loctite brand two part epoxy adhesive clamped up overnite, we successfully repaired the crack and were able to use the tool to complete the job. There is no sign of the repair failing after approx 400+ use cycles. It is much better to gauge overlap spacing from the bottom of the plank rather than from the top as the major competitor of this brand does. We set our Gecko gauges for a 6" over lap and had no trouble maintaining consistent spacing which is very important to a high quality install. Check your work for level every 4th or 5th plank as there is some minor variation in the Hardie plamks. It is easy to correct for this with the gauges. Level variation is observable if over 1/8th inch, so check your work as you go! I will not do another Hardie siding install without these "Gecko" gauges. Highly recommended.
