Pulsar RöK Silicone XL Extended Cloud Collar has a rating of 4.7 stars based on 3 reviews.
The extended version of the silicone cloud collar gives you more space between the carb cap and the coil than the original. This extra space allows you to use almost any carb cap with the RöK.
A beveled edge on top combined with the flexibility of the silicone gives you a great seal with your carb cap. Provides increased airflow, excellent vapor production and ultimate control over your dab.
Made with food-grade silicone and provides an exact fit with your RöK Electric Dab Rig.
For an even better setup add a carb cap tether which is compatible with the Cloud Collar.
