Searching for 21007 (x3)

The bi-fold pins you show are similar to our Benchmark brand pins. See our 21-002 and 21-044. You also mention the 21-007 in your heading, which is a Slimfold brand part. See our 21-001, 21-154 and 21-007. Carefully look over these parts to see which brand is better for your door. If you are not sure, see the back of your door for the name plate.
