Review on 🔒 Wheeled Cord Lock Stopper: Multi-purpose Cord Locks for Drawstrings, Paracord, Bags, Luggage, Shoes, Clothing, Twine & More by Matt Heringer

Wheel - Delrin I would say the case is a different nylon plastic. Details are quality. Works well with Paracord 550. Paracord 750 would be too thick for this lock. Easy to use and won't break when pulled like spring cord locks. If the wheel is supplied removed from the housing, thread both ends of the cable through the housing in the correct direction and then insert the wheel into the housing until it fits into the groove. It will not fall apart even under heavy use.
