Lenggeman has lime green caps, only place I have found that color. I can't answer about durability yet. Using 2in Bernstein alum for sec cors.

Thanks for letting us know. I looked for awhile for lime green caps, and never found any when we went in business. Everyone in my area sets yellow, orange or red (one guy sets maroon because he is an Aggie grad). We wanted something different, but we settled on orange. I'm thinking we will switch to green on the next order.
I only know of 2 surveyors to set aluminum caps in our area. One retired probably 20 years ago the other 10. Their caps have always been hard to read, that's one of the main reasons I never wanted aluminum.
I do leave caps above ground a tenth or so when around wire or steel post.
On a side note I found a plastic cap( not sure of brand) that was 15 years old that was sun rotted and could make out the name and number. I took a pic with my phone within a foot of the cap and zoomed in and was able to make out the name and number.
I would love to post a pic but I found this uncalled for rod about 12' from a buried called for axle and the only info I can get from the surveyor that set the rod is he did that survey 15 years ago and that file is archived in a storage unit.
There are a couple of guys in central Arkansas using those Morasse caps. While they may hold up well; I've had a terrible time excavating around them in our rocky soil to get flagging on them. Seems like a small complaint; I know. But, it's been enough to keep me from using them.
Plastic caps:
IF you lightly spray them, witj spray paint...
It blocks the uv rays...
Probably doubles, or more their service life.

That is what pin flags are for............
Kevin, I recommend one of these: http://www.homedepot.com/p/Estwing-25-in-Geo-Paleo-Pick-Blades-GP100/203075897
Their quality is second to none.

I order 1000 at a time and they are around 80 cents each and have had much better luck that with plastic caps. I have went back on surveys that were performed 2 - 3 years a go and can still read the laser etching on the top. We have started to grind a bevel on top of our rebar that makes it easier to start the cap, but that is done during rain out days while the guys are cutting the rebar to length.
By what method do they grip they rebar?

My guess is with their hands. That's what I'd do if I was using a bench grinder.
But if you use a rebar drive cap you don't need to grind a bevel, because the drive cap creates a nice smooth one during the driving process.

Ya know Jim I never would have guessed that someone would respond that way but I guess I asked for it by not being very specific.
I was referring to the laser etched caps from Bathey. They do not appear to have a plastic insert so I'm curious on how they grip the rebar.
FWIW, I took it the same way Jim did.

You can look at the picture on the website. On each side of the "stem" there is an indention. We use these caps, and I tested them first. You put one of those caps on a 5/8" rebar, and you have to beat it off with a hammer. It holds suprisingly well. The reason I like these caps is there is no worry about corrosion like with aluminum or brass caps, because stainless steel is still iron. You don't need the plastic insert.

Funny you mention maroon, I bought maroon for my first state(nd) being a U of Montana fan. I will probably never set one there, but looking back they aren't the best color to use. I think pink should be more widely used. Can't miss em. 🙂

Galvanic corrosion isn't that simple, and it can happen when stainless steel is in contact with non-stainless steel. A lot depends on which material is the anode, which is the cathode, and their respective masses. Small anode large cathode is the troublesome condition.

I second what Tommy said. The caps are sized to just barely fit on the rebar and the tabs on the sides of the cap grip the ridges of the rebar. Once the caps are put on, it is very difficult to get off.

When we cut the rebar, it puts a "burr" around the edge that makes it very difficult to get the cap on. The stainless cap will not stretch, so it makes it much easier to put a bevel on the rod. We use a drive cap but it it is much easier to spend a few minutes with the grinder.
