Catnic for 3.75m bifold

[Davidnewp]

We're having a 3.75m bifold installed in the rear wall of a single storey flat roof extension.

My question is whether a CX 50/100 Catnic will suffice. The concern is mainly whether it can take the concentrated load of the bifold when it's folded out.

The bifold is 3.74m long, 4 door - opening 1 to the right and 3 folded to the left.

Thankyou!

Do you know if the bifold is floor supported or suspended from the beam/lintel above? You need to check if you don't already know as they do vary.

It's an Alunet BF73, the website suggests it sits on the wheels at the bottom, rather than hanging from the top but will ask them tomorrow.

Alunet confirmed its not top hung. I've also spoken to the Catnic Technical department and they said would be sufficient to hold the load given its not top hung door.
