Kyle,
We (attempt to) show the first four components of Lisega's support designation:
1st - Product Group - all springs are "2"
2nd - Model - smaller hangers are "1" and supports (cans) are "9"
but bigger sizes are "2" and "8", respectively
3rd - Load Group - smaller sizes run from "1" thru "9"
(we do not include the smaller "C" & "D"
bigger sizes are "1" thru "5"
4th - Travel Range - "1"=short, "2"=mid range "3"=long
(we do not offer the incomplete "4" & "5" series)
You can find your spring in the Lisega catalog under the column labeled "22 1. 29". We will not show that trailing "29" - that indicates "Field of Application" and "Product Series". (The period is the place holder for the Travel Range.) The spring data is OK, it's just the label that's off. I will submit a request to correct this.
