How to Thread a cord lock
In this tutorial, we learn how to thread a cord lock. First, tilt the cord lock up and find the two different wheels on the inside of it. Now, push your lift cord up through the two wheels that are on the inside of the lock. After this, pull the thread up through the top and then slide the thread through the smaller hole on the lock. Now, you will repeat this again for another piece of string, but thread it through the larger hole once you reach the top. After this, thread another cord through the lock and again into the larger hole. After this, take all the strings and tie a knot by the bottom of the lock. Now, install into your board and you're finished!
