There's a guy in Quartzsite that sold a 22' HD for several years with spring push buttons. I bought one and it was great till it was destroyed by someone attempting to retract it and didn't know the buttons were there.
Anyway when I tried to replace it he said he got away from the buttons because they had lots of problems when mixed with sand (i.e.-Beach, Desert, etc.).There was another mfgr that said the same, so with tears in my eyes I bought a standard pole and drilled it. I bought very expensive SS pins because it's at the beach allot.
As for the holder, I bought this thing from him shown below. It's got milled and anodized mounts holding an inset PVC pipe that I painted and have probably 15 coats of clear on. I also have the Poles and Holders upper 2.5 mount that keeps the pole from banging around. Guarnteed THIS mount will NOT break
