Reading the reviews of this product before I purchased it, I expected to do some modification to the item before deploying it in my home. The adjustable peg that keeps the inner telescoping bar extended is the most vulnerable part of the bar. It slides in and out easily, and as others have said previously, can simply fall out of it's mount inside the bar, rendering the device completely useless. So, after adjusting the bar to the proper height, I drilled two holes through the bar and bolted the inner tube in place. Now, even if the original peg fails, there are two bolts to take the shear stress. Also, the bushing on the inner tube (to keep it from wobbling) is only loosely press fitted. I applied adhesive and reinserted it, now it remains in place firmly. With these changes, I attempted to break down my front door without success. In fact, the door frame started to buckle, and the bar didn't show any signs of fatigue.
