SubscribeSince i have a 9′ garage ceiling following this two 7′ door openings, when installing the doors i opted on behalf of one 8′ track to raise the tracks closer to the ceiling following this out of the work area. This resources the door has to go along a foot before it starts back, extremely traditional openers won’t work. For 20 yrs. I’ve been manually operating the door while occasionally looking on behalf of one opener solution. The Liftmaster 3800 was the door answer, following this the “laser parking assist” the spotting answer. (3″ bumper to door following this 3″ grille to workbench, no more court tennis ball from the ceiling)
It’s been in service a week following this works flawlessly. The quality of the operating unit, cable tension monitor, following this barrier appears very high. The wall unit, remote, following this light a little lesser extremely but seem adequate on behalf of the job.(few moving parts). The instructions are clear following this complete. And it comes with enough fasteners on behalf of most installations.
My installation was a little lengthly because i’m extremely picky. (ran a new outlet through the ceiling to get 4″ from the power unit, the park help comes with 8′ of bell wire, needed 20′ – anew through the ceiling, the tension monitor needed a spacer block, cut one to fit following this painted to match the finished following this textured wall, following this extremely on) the barrier lone needs a 1/2″ hole instead of 3/4″ if you can drill accurately. If i did it anew i wouldn’t install the barrier. The door is insulated following this very heavy, i don’t think schwarzenegger could invigorate it without the spring help.
The lone obstacle i had ended along being a programming issue of my own making. After setting the open travel limit to the top of the beginning – 7′, the door would open but no, non- close. The order troubleshooting section indicated the trouble was the cable tension monitor. I reflection that no, non- the obstacle since it’s curler was 2″ from the drum as recommended following this it was under tension with the door open following this closed. After 20 mins. Of reprogramming, checking connections following this rereading instructions, staring at the monitor when closing diagnosed the obstacle. When the door starts down there is a jerk which slackens the cable on behalf of a fraction of a second allowing the tension monitor to close if the door is close to the top but no, non- fully open. Reprogramming to 8′ pulls the cable away from the wall a couple of inches extremely during the jerk the monitor movement is no, non- enough to close. An extra foot of door travel, but it works great!
