Review: So good, so worth it. - So good, so worth it. It's like having 4 hands. Going up a ladder with a plank, a nailer, and a level, you still do not need another person to help you with this. If you are working alone, I actually am not sure how you side the house without these. I'm sure you would have to fabricate something similar. Even working with another person, I found these to be amazing. Have the other guy be cut man on the ground, and keep sending you up pieces that you set perfectly each time without having to re-measure. For the first 1/2 of the house I did, were were constantly re-checking level, and our layout and it was a good thing we did, these gauges take getting used to. Make sure you flush the gauge all the way up to the bottom of the board. Sometimes they can sit in an angle, and that 1/8th inch on 1 board can get out of hand in a couple rows if you aren't paying attention. Also make sure you keep the height adjustment bolts tight. I actually lost one of my plastic washers, but was able to find the bolt. Probably not that hard to replace, but just a hassle. If you are going to have these higher than a few feet over anything but grass, buy these and not the plastic ones. I dropped mine on concrete from about 20 feet and dented a corner, still works perfectly. These hold real well, I felt comfortable in how well these held on to slide in 12' boards from a ladder 10' away. Even with the tight grip, there was no damage to any of the boards. The locking handle moves super easy, doesn't take hard wrenching or anything that could be problematic on a really high ladder. Does only 1" increments for reveals. 5",6",7",8". Probably not an issue for most, but something to keep in mind. Still an excellent tool for holding a plank in place, even if I had to fudge a board 1/4"-1/2" or so to adjust my layout. I bought these for 1 siding job and found them to be worth the money. I sold them to my carpenter for 50% cost, but I'm sure you could do better if you wanted.

## Questions & Answers

**Q: Can anyone tell me where to get the extensions for these to do 12" siding .  I am in Australia so need to get them shipped here**
A: Bishop supply Panama City Florida.

**Q: This tool has horrible reviews. Does it work at all? Has anyone made it work?**
A: Yes. I made it work by hooking rubber bands from the side bolts under the lever to hold the tension to keep the gauge in place.  While it sounds a little Mickey Mouse, the gauges are actually a huge time saver especially if you are putting the siding up by yourself.  If you are using pre-finished Artisan Hardie, the other tip I can give you is to slip a thin shim between the boards at the base of the gauge to lever the boards out a little when installing or removing the gauges.  This keeps it from marking the boards and requiring touch up. I would definitely recommend these if you with the above provisions.

**Q: Is the green one is plastic? Or aluminum**
A: Plastic. They also are longer than these, which may or may not be good.  The plastic has more adjustments as well, but these could be drilled to offer more possibilities.  The aluminum ones seem to scrape more when you remove them, so would not be as good on pre-painted boards.

**Q: would these work with the sa90338 or the sa903?**
A: No, design and construction do not match up.
