Solid unit, installation takes time

The spring itself is very robust and feels like it will last forever. Installation required precise drilling into the concrete floor, so plan accordingly. Once installed, it works flawlessly.

Reliable and sturdy

We replaced an old failing spring with this model. The difference in performance is night and day. The door closes securely every time without slamming.

Exceeded expectations

Using this for a framed door in a busy office lobby. It has handled thousands of cycles over the last six months without any loss in tension or performance.

Great value for the price

Compared to other brands, this offers the same durability at a better price point. The adjustable speed settings make it easy to customize for high-traffic areas.

Perfect for heavy glass doors

Installed this on a 12mm frameless glass entrance. The build quality is exceptional, and the closing action is smooth and quiet. Highly recommended for commercial use.

Good product, clear instructions needed

The hardware is top-notch, but the included manual could be more detailed for DIYers. I had to watch a video to get the tension adjustment right. Otherwise, excellent product.
