VapeLock Double Duty – Heavy-Duty Retractable Clip (Patent Pending) is built for those who prefer strength, longevity, and a touch of overkill. It features a metal retraction cord instead of nylon and a redesigned connection system where the key ring attaches directly to the main loop of the silicone, eliminating fragile eyelets that never last. With a much stronger retraction mechanism, this model is engineered for those who want to carry heavier devices securely and confidently. Despite the added power, it remains lightweight and compact—strong enough to handle serious use without feeling bulky. If you don’t need this much pull, stick with the original model, because your biceps might actually get bigger from using this one. Simple assembly, some dexterity, and the ability to follow basic instructions are required.
