hi all I have a small 20x19 detached garage that isn't big enough for 2 cars and the driveway is too short to park a car on. The rear of the garage has an asphalt pad that can be used as a parking space but I'll need to be able to drive through the garage to get there. SO, i wanted to install one of those roll up security doors you see on storefronts and autoshops. My question is: can i just cut out the wall and install the door or will i need a header beam? The garage is a 20x19 wood box with pitched roof and the walls are build on a raised foundation. I was thinking a header beam with additional 4x6 posts at the corners and edge of opening will suffice or do I need to get a structural engineer out? Thanks.

Hello everyone, i have genie silentmax 1000 revolution series opener in my garage and it was working well and all of sudden it will not close. Force pressing the wall button will shut it down. I have spent a number of hours on the internet and going through the manual and it seems like it is a safe-t-beam issue. i have GSTB-R model beams, with one green which is steady and the other red continuously flashing. I have checked every damn angle to confirm the beams are aligned correctly but it wouldn't just work. I have so far done the following - tried to re position the beams by moving a bit of them but it just does not stabilize. - I ended up removing the red blinking sensor of the wall and placed it next to the green beam it will still keep blinking and will not stop. i mean literally made them to kiss but it remains blinking. - used windex to clear the lenses but no luck. still blinking. i can force close the door by pressing the wall button but i have now run out of ideas what next to try. The manual suggests to check the limits but i do not want to mess with it unless i know this will fix it as the door when forced closes to the correct limit. I see the replacement sensors are $38 which i am ready to throw but anybody has any ideas on what to try next? Note: i recently washed the garage and after that the door has worked fine for a few days (may be 4/5 days after that).
