Loose caps on rebar

The last two orders of caps I purchased for 5/8" rebar slide easily on and off the rebar. One order was from Stakemill and the other from Berntsen. Since both call for a model 5000 with either Permamark or PM I suspect both caps are permamark caps. We've tried rebar from three different suppliers with the same results.

Has anyone else experienced loose-fitting plastic caps?

Mountain Mold and Dye make the best caps that I've ever used and they have a wide selection?ÿ of styles to choose from in most colors

I am an orange person and when I found some blue ones our in the woods I was surprised at how they popped against the foliage.

I have been leary of some rebars out there, we buy caps in SAE sizes and many of the rebar on the market is in metric sizes and are a little off from what we are used to.

Have had to wrap a wad of flagging around the top to get some caps to fit in the past.

Thanks. I'll check into Mountain Mold & Dye. We wrap the rebar with flagging to make the caps fit. It's a bit labor intensive though.

@gradetek

A bit of tie wire folded over the bar probably work better and faster, if you carry wire and dikes anyway, which I often do but may be in the minority.

I would suspect the rebar, not the cap.

I am having to order rebar caps, again.

Which brand lasts the longest, in the sun?

Thanks,

Nate

I'm not old enough to know the answer to that question.

There's 3 ways to tell yer gettin old.

1.) Yer memory goes.

2.) I don't remember the others.

that's my first thought as well.  I used to get the aluminum caps from Surv Kap with the plastic inserts that made the connection much better.

Hard aluminum or brass

If they're in direct sunlight much of the time, any of them will eventually degrade.  Around here we have pretty intense summers, and most of the unshaded plastic caps set in the 1970s have crumbled.  So if 40 years is long enough for you, then plastic is fine; if you want more durability you need metal.

How do those aluminum caps hold up in a fire?

 

Not that plastic will do any better...

@dougie 

I recently did a fire survey, plastic melted, metal caps, aluminum or brass were fine. I pulled one out that was plastic for a section corner, I thought it was a tree root at first, it was weird looking.
