Solid unit, instructions could be clearer

The floor box itself is incredibly sturdy and looks great once installed. I deducted one star because the installation template was a bit faint, making the concrete cutting phase slightly tricky.

Great value for heavy-duty use

Compared to other brands, this offers better adjustability at a competitive price. The stainless steel finish resists scuffs from foot traffic very well.

Perfect for high-traffic entrances

We installed the large size on our main entrance, and it handles the constant flow of customers effortlessly. The build quality is exceptional, and the adjustment features made calibration simple.

Reliable for commercial projects

We have used these in three different restaurant builds this year. They are durable, easy to source in different sizes, and hold up well against heavy daily use.

Exactly what we needed for our franchise

Ordered the medium size for a side exit door. It matches the specifications for our existing hinge bearings perfectly. Very smooth operation and quiet closing action.

Smooth operation immediately after install

No break-in period needed. The door swung smoothly right after we finished tightening the screws. Highly recommend for anyone upgrading old floor springs.
