[GreenKeys] Casters for M28 Teletype equipment

Sat Feb 1 19:02:52 EST 2014

On casters  this is what we  have dome    and a  perplexing  caster to a 
19" equipment rack   problem.

Our  casters at SMECC We did 2 inchers on the krs and  3  inchers on the  
asrs...  Yea  the  3 inchers  look  a  big  large.

One of  our   19s   has  3/8 16 stem  accepting...  I ordered these bright 
red  things   I think I  will use them on a  rack  instead...   they  clash  
with  WU green!

We have a weird  problem  with a rack  cabinet...   it  has threaded   
things on   bottom....  the  1/2" stem  ones that we use on the asrs   also  fit 
 one  rack BUT  NOT THIS  NEW ONE...   And  the   3/8 "  x 16   stemmed 
casters are   too  small..   Has anyone  found a   caster stem  threaded   size 
between the  1/2" and 3/8?

I order  one set of 2 inch and one set of 3 inch.  I think the two inch 
visually  look better on the cabinet (the 3 inch look too large IMHO) but I 
prefer the  way it moves around with the 3 inch. 

The wear pattern is interesting.  The 2 inch has wear all the way across 
and uses the entire width of the wheel  (the wheel is flat across), while the 
three inch has a 1/4 inch strip so it is  only using a portion of the wheel 
(the wheel is slightly v shaped).

Not  sure which would be better for wood floors.

purchase casters for my M28  KSR and ASR.  What did you guys end up buying? I 
think I read that some  of you bought the 2" size with no brake.  I am 
looking at these two  currently:

There may be others too, I didn't look  at everything in the catalog.
