I use my telescopic stands a lot as jack stands with the inner telescopic tubes at their lowest position.
Today the need arrived for me to have 1 of them partially extended to support a small pickup But I won't ever trust a friction lock with my life.
So I decided to incorporate the design of some of my other safety stands into this one by drilling a series of holes in the tubes. Now I can extend either or both to their fullest height and pin them in place and still use the jack screw for micro adjustments of use the screw as a jack to lift the vehicle
There has been more than one case of blood from the less than positive lock of the friction lock on those style stands at my bosses shop. Last time put the employee out of work for about a week if I'm not mistaken. Messed his hand up. Have to say I like the pin idea quite a bit, thanks. The stands get used and abused. Last year a job came through for 36 inch sch 80 concrete lined pipe. They bought some new stands for that job. Can only imagine the carnage otherwise.
I used to manufacture pipe stands for use in the oilfields in the Middle East. Our most popular were the multipurpose folding pipe stands.
They were beefy but lightened every where it was not structurally critical
here are some pics of the drawings of the assemblies
The plate can be flipped up to serve as a flat surface for when working with structural steel other than pipe

in this picture you can see that the 2 rollers can be positioned either close together or further apart for larger diameter pipes
in the telescopic tube there are a series of smaller holes as well these can be used to place a lynch pin for safety when dealing with heavier pipes

Very cool design on the pipe racks Frank! Seems like Maximum versatility to me. Am totally agreed about working under Stands and trust no one to place them for me. A good friend lost his life in Albuquerque a few years back working under 2 and pulled too hard with a breaker bar is my understanding.
