If it the trigger sticks you are inquiring about
I just checked one of my sets
Primos tall tripod trigger sticks
39" without the yoke
41" with the yoke
2 lbs 13 oz
I have two sets
Extremely strong air cylinders have never failed me using as walking sticks in the Rocky Mountains.
The length is instantly adjustable
From 66" tall monopod with the legs bound
To as low as 23" as a very wide tripod
I've used them all....the tall tripod trigger sticks are leading the pack without any doubts
