    Adjustable angle make this roof jack easy to install and eliminated the need to have a sheet metal shop make one for me. A couple of places needed silicone sealant to close small gaps. I also sealed all the seams and screw heads to prevent water from entering the jack, as when snow might pile up against it.

    The 1/4″ diameter sheet metal screws provided with it seemed overkill to me. 1/8″ or 3/16″ screws would have worked just as well. The optional slide in damper is a very good idea and I bought one. I had to do a little bending on the access door to get it to fit tight against the front of the jack.

    Otherwise, it works as advertised.

    The product came with an instruction sheet and all the hardware. It was easy to understand and easy to install. It works great.

    The roof jack is relatively easy to install but would be a better product if it was made of heavier gauge material. Be sure to install the appropriate leg support kit or you will regret it.

    Arrived like some one took a bat to it. Bent it back and it worked but the shipping from fed ex box was very damaged

    Excellent strength, durable.
