Before I had the door anchor, I made the Theraband a loop and pushed through this a pen. About the open door I put the strap to the pin on the other side of the door and the door closed. After just a few applications ripped the Theraband a on the side. The sharp edge of the door had damaged the tape. Since I use the door anchor, everything is fine. So far, the anchor is still intact. The tape of the anchor is very stable, while the round disc makes a less sophisticated look. I hope he keeps the continuous load from. I will like to add to the recession, if there is not something new to report.
