What angle is the braket at the sofa position? Are their videos of the bracket?

The best answer I give you is a guesstimate. With the plans I used. It looks like it came out about 100 degree angle.

Does this come with any instructions? as a diy, instructions would be nice.

It doesn't come with screws and I had to use original screws

Fits DHP futon

Had a DHP/Better Homes and Gardens wooden frame futon and broke a hinge, this bolted right up and works as good as new.

Prompt service.

These mechanisms for the futon bed are amazing. Heavy duty, work great for our sons bed. He is a tall and heavier teenager. Installation was very straight forward, springs all work, and the bed converts so easily. Thank you Prompt service and came earlier than expected.
