    I should mention that could be a real concern for me living in Vancouver lol. The months of November and December together average 13.78 INCHES of rain, and that's just an average. So safe to say lots of water in the air too, but I see your point

    I use a PVC tee with two holes in the horizontals and landscape nails driven through the holes to secure it to the ground. To secure the pex to the tee, I drive two 1” drywall nails into the pex through the vertical part of the tee. If I had to waterproof, I’d probably just squirt a plug of silicone caulking into the pex above the screws. My strips are in sealed silicone sleeves and I’m in Arizona, so I don’t worry too much about any further waterproofing.

    I am putting Pex Arches for the first time this year in between my candy canes along the side walk. For ease of set up, I have put 1-1/4" pvc pipe in the ground and screwed a piece of 1" pvc pipe on the candy canes. 1" pipe slides into the 1-1/4" nicely. So I have now attached a 1" Plus Fitting onto the candy cane with a piece of 1" pipe running vertical. On the Horizontal I have attached a 1" x 1/2" 90deg elbow. The 1" pex tubing fits over the 1/2" PVC Pipe with a small bolt through it to keep it from twisting. I drilled a hole through the bottom of the elbow to allow the connector for the lights to fit through. I figured the hole there will allow any water to drain that might get inside. Lights are water protected so not too worried there.

    I'm going to update this thread as to my original query as part of the paying it forward philosophy. For my particular needs, my arches would be mounted against a railing, so I don't have to worry too much about keeping them upright or weighing them down, mostly just the two ends connected at the base to prevent them from snapping back to straight shape of the original pex. Last season, I was looking for an alternative to pixel mounting strips because of the cost of shipping, and came across a post recommending using this plastic pipe hanging strap you could buy from any hardware store. It was grey with 1" spaced small holes, and I simply used a forstner bit to drill the holes to the right size to mount pixels for my megatree. Even with 50 holes drilled into it (whose edges only left a very thin strip of material connected to the rest of the strip, not only did none of them break, but they withstood a pretty decent amount of tensioning in weather that spanned -20 Celcius to +15 Celcius over the span of 2.5 months, including rain, snow, you name it. And still this year, when I pulled them back out, they are just as strong, not brittle. I saw so many people talking about having to put a piece of emt as the base, and although it completely depends on your application and situation, using this dirt cheap strapping appears to be a good alternative I can report. I picked up some standard size adjustable pipe clamps for around $0.25 (and that's Canadian, Americans can probably get them for even cheaper). One on each side of the arch. Loosened it, slid the strap between the clamp and pex, tightened. I then proceeded to abuse the heck out of the connection to a scrap piece of the same pex and whipped it around like I was Indiana Jones lol. Doing everything I could to see if I could get the strap to break, the clamp to slip off the pex, or the strap to slip out of the clamp, including using it like a lasso and hitting the ground....Nadda. It's still holding firm. Connected it to the other side of the arch and it's rock solid thus far. So there you have it, a dirt cheap alternative that allows you to adjust the width of the base so you aren't stuck with whatever size your emt was cut at. But keep in mind, it all depends where you use it. Some places, that extra weight is needed

    Here's the link to the product from the Canadian store I got it at, but just use that for reference. I've heard the exact same thing is available pretty much everywhere https://www.rona.ca/en/3-4-grey-poly...-strap-1120027

    PS EDIT: If you ever here a Canadian referencing RONA.... Rona=Lowe's in the USA. I'm pretty sure they are the same company.

    Iím now more confused. Are you using bullets or strips? Are the LEDs inside the PEX or outside?

    Just having trouble understanding the need for the added straps...

    Sorry, I'll clarify. For my arches, 60LED/m pixel strips ws2811. Running inside the pex. Originally, I had been asking about material/types of setups for the brace at the bottom. This isn't "added straps". People often were talking about using emt conduit for the base of the arches, the section that holds both ends of the pex pipe into the arch shape. I was looking for an alternative to having to use the emt. The strapping was something I had left over from the previous year, and I thought, why not, nothing to lose by testing it. And I discovered it to be a light, strong and dirt cheap material that allowed for adjustments. Nothing more, nothing less. Just like you wouldn't want to use emt in every case, you wouldn't want to use the strap in every case. I was just letting people know my findings. And I literally was doing an indiana jones lol. Holding on to the strap with my hand attached to the pex and whipping it around in circles trying to see if it would snap or detach

    Never claimed it was perfect material and picked for the purpose. Already had it and figured nothing to lose and so far, quite impressed

    The question was out of curiosity as the link you provided lacked detail . I don't have arches , so am of no help in that regard .
    Your photo answered my question . Thanks for posting it .
