15 mm diameter carbon fiber tube. One 20 inch tube weighs just 36 grams or 1.25 ounce. Wow, that's light. The tubing is centerless ground to our specs for excellent fit and is very strong. Ends are capped. Made in USA. Rods sold individually.
You get what you pay for has never been more true. Finishing touches like end caps for the rods - that fit on the inside and don't add anything to the OD - are what makes Berkey System the best!
