Small cam-lock cleats.
Want a great tent guy rope tensioner? Try these cam-locks. Feed your guy rope through the small hole, wrap rope around the peg or fixing point, back up through the other hole and lock the cord into the jaws. Simple to use and easy to release, just pull up on the cord. These cleats can also be screwed down and used for a quick release cleat.
The cleat will hold 2mm, 3mm and 4mm paracord very tight
