Ladder parts need replacement

[TXredfish]

On my motorhome ladder, I have 6 of those black plastic inserts on the ladder rungs split. It has 3 screws. 2 screws hold the plastic and the middle screw holds the ladder rung onto the vertical tubes. Does anyone know where I can purchase these plastic inserts. It has Kemberly Inc on each of the inserts.
I have tried searching IRV2 and googled Kemberly without much luck.
Thanks ................

I just bought four of them from a local RV dealer, had them in stock like $2.50 each. Very common ladder shouldn't be to hard to find.

I have checked with the 4 RV dealers in town and no luck. I called Newmar and they are going to ship me 6 at $3.50 each. Thanks ...................

TXredfish......Atwood sells what you're looking for. Several years ago, they sent me a bag of ten for free and said I would have to pay for the next order. They must be better quality because the set they sent me have lasted for years.
