These are very nice banksticks/storm poles. Beefy, inside and out. The outer diameter is 3/4" and the inner post is nearly 5/8". Locking mechanism for the height is a T-Lock screw bearing against curved plate. Positive locking without marring the inner post. Stepped point makes it easy to stick into the ground.
Quick Release Top Cup screws onto your buzzer or rod rest and stays attached. A quarter turn or less of the T-Lock Screw releases the Top Cup and a quarter turn removes it. Additional Quick Release Top Cups and T-Lock Screws are available so you can have all of your alarms and rod rests set-up for quick attachment and removal.
