I'm sorry Danny, I'll get that taken care of!



by:

Looks like quality rubber. Solid thick rubber. Much better than what is being replaced. Does not appear to be the cheap Chinese smelly stuff that falls apart in two-years. Time will tell.



by:

A little different than the original,but work satisfactory. It was a bit difficult to install due to my inexpensive and cordination. Next



by:

I’m still installing rubber seals on slide out. Product is superior. However, installation videos should show people doing the actual work, not just talk about quality and dimensions of product. Rubber is hard to slide in tracks. You should recommend a lubricant or demonstration to allow a smoother installation.

  • Looking for Replacement Slide Out Seals for 2020 Heartland Mallard IDM251BH
    Hey Greg, yeah replacement parts for RVs is like that unfortunately. There just isn't the same type of database available for replacement parts like vehicles have. So for seals your best option is to identify the type and size of your slide out seals and then from there we can see what you'd need as generally there are only a few different types. I attached a link on this page that has all of the seals we have but you can also email me back with the pictures you mentioned and I'll take a look.

    Hi Darlene; to find if the Rubber Wiper Seal with Track for RV Slide Out # SR39FR will work for your 2019 Thor Four Winds 24F you will need to compare it to what you have now. This is a 3-3/4" wide wiper seal with a stick on installation. If your wiper seal matches then you can expect it to fit and work with your motorhome. This can be used with the # SR74FR to keep it weatherproof when closed. It does not require a professional for installation, but I recommend an extra set of hands...
