Ben,

There are a multitude of laser levels (in a multitude of forms) available to do what I think you are trying to do.


The 110 feet might be an issue but if you are consistent you can probably plot the location for halfway and then repeat the process for the second half. Perhaps there is already a level that accommodates the 110 foot range in one effort? Best wishes, let us know what you decided and how it turned out.

Hello Wrenches,
Wondering if any of you have ever done anything similar to installing on a vertical wall using a horizontal shared rail racking system, array being about 32.8m (110') wide and 26.3m (86') tall

The rails obviously have to be exactly perpendicular the entire length so we are taking extra care that the first row (top row) is true and using template spacers for each row down. Only problem is that the top of the building is a concrete parapet and anything but level.

Wondering if anyone has any good tips for getting that top row level/square and keeping the rest of the rails perfectly perpendicular? (keeping in mind the length...32.8m (110')

Much Thanks,
