Tool works great. But we ripped through the pvc pretty quickly.
Dale Horning –
Thanks for a great tool. Really like having one tool for both stages that works well. Takes less effort and looks great. No need to get out the power seamer for short runs
Sam –
I am really liking this tool. I hand-formed panels with a custom profile, and am using this tool to perform the first and second stage locks on 26 gauge galvalume, with 26 gauge stainless steel cleats. For my particular panels I tilt the tool slightly to get the locks started. I make two passes for each lock, one is a partial lock, and then the second one is where I really clinch down the seam. I am not a roofer, just a DIYer. I would recommend this tool.
Tyler Flynn –

We have been using this seamer for a double lock seam. We are very happy with the performance of it on both stages of the lock.
Todd Whitney –
This is definitely the seamer to have if you’re doing a painting standing seam. No worry about scratching the panel as you move along and it gives you a very tight seam. Excellent seamer.
