Little Giant Ladder Accessories

I have a similar multipurpose ladder made by Werner. Anyone know if the Little Giant parts are compatible? I’d love to have something to hold the tools while I’m at the top!

No unfortunately I don’t think they are. If you look at the images the pieces that connect the parts to the ladder look like they’re specifically made to mate with Little Giant systems. So unless your Werner ladder broke some patent laws and has the special connectors it won’t work.
