Review on 🧼 Efficient HV601 Brushed Kitchen Sprayer: Optimal Material for Enhanced Cleaning by Christopher Lance

We followed the instructions and installed the faucet on the sink only to find the part still in the box the faucet came in. Using Google Lens, we found out it's a sink stabilizer. This stabilizer was not mentioned in the instructions and is not shown in the drawings. We tried removing the lower brass ring to insert the stabilizer bar but couldn't. I'm worried that without a stabilizer, the crane will sway. Why wasn't it mentioned in the instructions?
