Barn Door Stopper 2PCS for Top Track Sliding Door Hardware Accessories Flat Rail Roller Stop Limit Device Black

This product worked great for what I needed it for

Took maybe two minutes to install and are super sturdy! The spring feature makes it impossible for the kiddos to slam the door shut.

Our hanging door system came with stoppers that enclose the entire sliding bar - meaning the bar has to be taken down to get them on and off. Unfortunately, I didn't realize that until after installation. No problem - these slide over the front and hug the very top and bottom of the back - meaning they slide around bolts. And they look much better and include a spring stop - unlike our original stops.

Works well

Forgot to install the stoppers on our barn door and did not want to take it all apart. These look fine and actually have a spring that absorbs some impact which the stock ones did not.

Needed a center stop over a through the rail bolt. No need to remove 40mm rail, just loosened the allen wrench screws, and it was even clear of the bolt. Tightened the screws just fine. The plunger also gives it some width variation in this case, might cause a little bounce back, door is heavy enough and basically absorbs the "shock", such as it may be called.

I like the soft bounce of the door against these better than the hard stop of the original ones that were supplied with the door.

The original door stops were just small rubber stops on metal piece. The spring loader plunger takes the force easily
