A lot of construction projects are judged by the amount of time they will take in beer units. "Sheetrock the den- a case and a half". At eichlernumbers.com we think the proper unit of time for mounting the numbers is two Tootsie Roll units.
1. What you need is a small level (for those in the know, a torpedo level works best), and a #2 phillips screwdriver. (Carmen calls them + screwdrivers, as opposed to - screwdrivers)
2. Eye level (60" off the ground) looks best for the height. Check to make sure no one is watching and pop the first Tootsie Roll in your mouth. Attach the numbers to the wall with one of the screws through the predrilled hole.
3. When it's snug enough you can let go of the address panel and straighten it to a level condition. Center the bubble on the level that is resting across the tops of the black number tiles and screw in number two.
Studies show that addresses that are half a bubble off may result in more junk mail coming to your house, and we all have plenty of that.
4. Open your second Tootsie Roll, pop it in your mouth, step back and savor the moment. That's it.
