Recently got a Altaplex and Zpacks seems to always be out of these pole jacks online. So I hit up my hardware store and found some 1/2 inch pipe with a screw on tip. Weighs 2.3ozs and it a total of 8 3/4 inch long. However, after inserting it on my hiking stick it only gives about 5 1/4 more height. I think 10 inch would have been better so that my trekking pole has more stabilization, but the 8inch is bare minimum. Bigger is better I guess!
I’m using the Black Diamond Ergo Flick Lock… I extended each hiking pole section to 135mm to get to the recommended 58inch height for the Altaplex. The maximum height of my pole is 140mm. The 1/2 inch pipe fits perfectly over the tip. Snug fit. The PVC pipe seems rather tough and would stand up to a storm. Only weighs slightly more than the carbon fiber. Anyone try this in the field with good results.
