There is a 30 day free trial when you download and install.  There is only one install and it will install for all versions of Tekla from 2016i and newer that are installed on your workstation, or you can choose which versions of Tekla you want it installed on.

Version 1.2.0 has some small bug fixes and will work in Tekla versions 2019i and 2020.

This plugin helps you to create hanger or brace rods easily with different style clevises, hillside washers, turnbuckles, couplers, etc.

Here are some pictures.  Please review the help file after installing.  We will be adding some videos soon.
