Yeah, the tables will be gone soon..
The stilt pants in the vid are just one type, the 3/4 type don't cover the spring.
According to PoweriSer brand, maintenance should be done by a dealer, and or only with PoweriSer brand parts. The average person will probably not order off for (sometimes expensive) parts that are cheap and readily available at the local hardware store.
Then again, if the stilts are still covered, the parts should be free...
Sorry, just needed to be blanketing.
