If you want to replace the hooks of your gazebos, here is the model we are selling. 

These hooks work on a rails system as you can see on the image down below. 

Please note that we do not sell these hooks by unit, but by package for logistics reasons. 

We have packages of 25, 50 or 100 hooks and the price includes economies of scale for the package, meaning that you are better buying 1 pack of 50 instead of 2 packs of 25. Unfortunately, it is not possible to add hooks to make packs of 30 or 40 because the packages are already made and we do not have access to unit hooks.  

Here are the measurements of these hooks.
