Yes yes, we know, you were moving your Gym1 core doorway unit around and one of the kids took it away and now your safety shim is long lost. Don’t worry, it happens all the time. We have them for sale but because of the size and unique shape, we can’t slip it easily and cheaply into an envelope so there is a shipping charge of $4.95 due the container it needs to be shipped in. You might want to consider ordering two right now just in case your next move results in another lost shim by your little tots!
However, if you’ve gotten pretty darn nimble putting up your Gym1 and taking it down, you probably don’t need this shim anymore right? It’s main function is to help when you are installing the core Gym1 unit; it helps with the blue plastic bar while you are tightening the important vise-grips to your doorstop ridge and your outer trim. So even though you’ve grown to love it, you can live without this shim if you wish despite it’s important sounding name.
