For your Benchmark bi-fold door, you are showing the bottom adjusting pin, our 21-002. You will need a pair of pliers to loosen the nut and a screw driver to raise or lower the door in the track. After you make the adjustment, you will need to tighten the nut. The other three pins will be 21-044 spring loaded pins. |
