Safety Pins for the bottom 3 Telescoping Tubes

We have added an additional safety mechanism. Each locking collar for the tubes has the ability to receive a locking safety pin.
As you raise each tube you will see the warning white line. It tells you to stop. If you try to go further there are stoppers that prevent the tube from coming out all the way. But once you elevate the tube to the white line and lock the camlock, you will see a hole visible. On the bottom three tubes we have included a safety pin for each of these tubes. When you insert the pin the tube is secured. It can not go up or down as long as the pin is inserted.
