The Screw In System Upright has a riveted threaded end at the bottom of the Pipe/Upright. This screws into Base to create one piece.
Our telescoping Screw In Uprights come in four sizes ranging from 3′ to 14′ H. The two-in-one system: Button Lock System and the Locking Clamp Systems provide flexibility to use the same upright for different heights. The Button Lock System has a button lock that slides up and down the pipe in marked one-foot increments and then locks into place. This option is great if you know your Pipe and Drape set up will always be adjusted in one-foot increments. The Locking Clamp System is also great – it allows you to adjust your Upright in-between one-foot increments.
For example, you can set your Upright to eight and a half feet which really gives you a nice range of flexibility. Instructions on how to use the locking clamp ship with the order. The Locking Clamp will ship assembled on the upright.
