Thanks for contacting us. The 81-183 does appear to be the strongest roller in this style we can supply. It has a 200 pound capacity per roller. This is compared to the 81-173's capacity of only 70.31 pounds per roller. I'm still waiting to hear back about the 81-163, but I doubt it will be stronger than the 81-183. I'll let you know as soon as we have that information, regardless. |
