I use the TRX ceiling mounting since a good week! I have been using the enclosed screws and dowels to mount two 12mm from the hardware store to the TRX ceiling mounting in a reinforced concrete ceiling. After initial skepticism, whether the TRX endures my 130kg, I realized that this is unfounded. Even initial rumschaukeln, with full body weight, were held without a murmur. The thing keeps rock solid and I trust the TRX now blind.
