The product features state: "One square supports up to 200 pounds."
The product description then states: "Strong and sturdy, one square has been tested to support 250 pounds."
These two statements contradict each other.
Elsewhere in the product description it says: "The prefabricated plastic panel squares are secured with screws to the attic floor joints to create flooring space for storage or a stepping stone pathway to get to hard to reach spaces."
Aside from the misuse of the word joints there they obviously meant joists, they are suggesting that their product can be used as a "stepping stone pathway" when the product is only rated for 200 or 250 lbs. depending on which info is accurate. It doesn't give me a lot of confidence in their product. Technical writers are not that expensive. They should either consult with one or fire the one they have.
However $37.00 for four such panels is not a large investment. Sadly, the product is not eligible for Amazon Prime so tack on another $11.84 for shipping. Order a 4-pack, try them out and if you like them order more. If you weigh in the 200-250 range, I would be real careful about stepping on them.
How is that for discussion?
