Dear All,
Thanks to all those how replied. Here is a summary of web-addresses
for suppliers of plastic chains and stanchions (they look like a
cheap plastic tubes to me, but stanchions they are...).
http://www.mrr.com/parts/stanchions.shtml
http://www.grainger.com/Grainger/start.jsp (then search by BradyLink)
http://www.labsafety.com (go to Signs and Labels > Traffic Signs and
Barricades > Indoor Traffic > Barricades)
https://www3.fishersci.com/catalogs/ (go to Fisher Safety > B > Barricades)
http://www.mcmaster.com/ (then search Plastic Chain)
http://www.globalindustrial.com/ (then search by Plastic Chain)
http://www.mrchain.com/consumer/plastic.htm
However, I jumped the gun and found this one on the web:
http://www.hpionline.com/chainproducts/
They were pretty good about getting in touch with me after I asked
for a quote on-line, etc., etc., so they got my business. Also, I got
30 feet of 3" chain and 6 posts (stanchions, pardon me) for $141.60,
including $15 shipping.
I also got a very clever and ingenious alternative from Charlie
Dickinson (UM-Amherst), which I paste here:
>I have found a cheap,convenient effective solution to magnet
>blockading and posting.
>
>For about $24 you can buy two 10' lengths of 2" PVC pipe and
>appropriate fittings--2 elbows and 2 T's and 4 ends...
>
>I like the white kind and clean it with a little acetone. I cut one
>up for ~3'legs and 4 6" pieces for 'T's at the bottom of the legs.
>
>Once you glue it together neatly and squarely you cut up some of the
>manufacturers magnet warnings and stick them on the cross bar.
>
>This has the convenience of being able to be moved out of the way
>with one arm in a single sweep. I have had several in my lab for
>over 10 years. They are sturdy and effective.
Again, thanks for the pointers,
Guillermo
