FCMS overlap guage set is great!

Fiber cement lap siding can be tedious.This guage system greatly simplifies it. I recently installed 1000,s of square feet of it on a recently constructed H#@ters restaraunt.It made a grueling job go a lot better.

Great tool but confusing marketing

I work alone most of the time. I purchased a set (thats 2 identical items) of the metal fixture (whatever it's name is.. overlap guage or facing guage) I do not own the plastic device. I use the 2 guages with hardiplank. The Hardiplank itself sets the overlap; 5-1/4" Hardiplank is used for 4" siding reveal, 6-1/4" Hardiplank for 5" reveal, and so on. The fixtures I purchased are indispensible if you work alone. The 12' Hardiplanks are heavy and, for lack of a better word, "floppy". The fixtures make quick work of putting them up. This is a must have tool if even if you are only doing your house BUT buy two of the metal fixtures and buy the right width hardiplank to get the reveal you need. Hint: Check the reveal every 2nd or third Hardiplank because as good as the fixtures are they are not perfect and an error can accumulate.

These are the most handy tool that I have purchased in a long time. It enables one person to install hardyplank siding.Great product!
