What is the max force this opener can push/pull? (I would like to use it on a solid wood, 41" wide, 7' tall door with spring loaded hinges - aka a fire-rated door between the house and the garage.)

Hi, there is no exact max force, here is a product manual for model Olide-120B:

Hi, Can this be used on a Front Door? Does this somehow work to unlatch the existing latch mechanism in order to be able to be opened? (I have a lever door handle) Which is the cheapest model you have that is controlled by large buttons near the door and by Google Assistant, please?

Hi Anna,

We have model olide-120BL that can work with your existing latch door, if it's for your pets, I recommend the package with smart pet collar tag:

It not only can use phone control, but also can connect with Google assistant. And for security, it's better to install an electric lock for front door.

Would it be possible to make a book case door and pull on a book and the door to open ?

Hi dear, could you please send me a picture of your door? So that I can confirm if it can suitable for your door.

Does this opener work with door hinge on right or left side of door ?

Hi Daer,

Both side are ok, it depends on your door opening direction
