To activate your Cordloc, simply insert cordage through the hole, compress the top to engage the spring, and use Cordloc as desired.
These things are great for helping cordage stay where you need it and at a moments notice adjust it.
Worked perfectly for my needs. Adding an adjustment cord to a boonie hat and fixing the existing one. Also going to add them to my boots for quick adjustment of laces.
Needed to replace the cordloc on my boots and the ITW worked great.
