Looking for a step by step "How to install halo lit letters on stone monument"

[Jean Shimp]

Looking for best practices on installing reverse lit channel letters onto a stone or masonry monument. Trying to quote installing 15 individual letters, stretching out about 16', on a new block/stone monument. Installing each letter is not the issue as we have installed non illuminated channel letters before. But what do you do with all the LED wires from each letter that exit off the back of the structure? Do you create a "raceway" or box to cover the wires and include the power supply (supplies) inside the box? Does that affect the UL rating? Thanks.

I put j boxes on each conductor coming out and link them with flex. This photo is a parapet wall but just imagine a monument.

Is that usually how it is done? Once that silicone on top of those boxes fails you run the risk of filling the boxes and flex with water from the backside where it penetrates the wall.

Ideally, when the next guy opens them up they will be filled with water, layers of bugs, dirt and exposed conductors ... At least that's what I usually encounter.

But yes, that is to code.
