You have the "professional" version of the tools....

In case you hadn't noticed , the ladder wouldn't have fit into the room where I hung our glass! In fact, I tried to use a yardstick to make sure I was getting them hung straight...even the yardstick was too long!

We have a level that's around 9" long, so that fit, and I used an 18" ruler...but I think the top right glass is a little crooked . I'm thinking a small piece of plastic between the glass and the clip should do the trick...
