Broan RVK1A Roof Vent & Cap Kit

Roof vent is easy to install but I replaced the plastic "claps" (wire ties) with 4"stainless steel hose clamps .

The kit was complete with just about everything thing I need. I did purchase some hoses clamp to hold the flexible ducting because I just didn't trust the wire ties that where included with the kit. I was having my roof redone when I was installing the kit so the roofers installed the vent so I can't comment on that part, but the rest was easy to install and use.

This is a great product because it is easy to install and covers most bathroom exhaust fans configurations. It has all the parts supplied. The mesh screen on the front keeps out animals, which is really important. The removable duct flange helps to make the installation even easier.
There is one drawback. They use to have a roofing nail hole drilled at each corner of the vent, now you have to either pre-drill(I suggest) or nail through the vent flange into the roof(Can bend the flange so that it will not sit flat on the roof.). They may have forgotten to drill this one unit.
