Roller doors ("Sheet Doors"-USA) are usually constructed of corrugated steel. They evolved from cover window and door coverings.[4] Other materials can be used (e.g.; transparent corrugated fibreglass) where strong impact resistance is not required. Corrugations give the door strength against impacts. A typical single car garage roller door has a preloaded spring inside the rolling mechanism. The spring reduces the effort required to open the door. Larger roller doors in commercial premises are not sprung (except USA) and use a manual pulley and chain system or a geared motor to raise and lower (roll up and roll down) the door. Roller doors cannot be effectively insulated.
Hmmm...Intro to E12...looks suspiciously like a freehand angled cut on that contractor saw... Yes, the riving knife might save you from a dangerous kickback...but still a very bad idea.. Why not a 'safety segment' explaining kickback and why you should not do this (styrofoam demo, back side of the blade teeth rising up grabbing the foam and throwing it back at you...)

Step 1: Check the metal tracks inside the garage. Look at the mounting brackets that hold the tracks to the walls. If they're loose, tighten the bolts or screws at the brackets. Working inside the garage with the garage door closed, examine the tracks for dents, crimps, or flat spots. If there are any damaged spots, pound them out with a rubber mallet, or with a hammer and a block of scrap wood. If the tracks are badly damaged, they should be replaced.
Response time was excellent. Alex was punctual, friendly, and knowledgeable. I had a 23 year old opener that I needed to replace. He came out and replaced it. It didn't take too long and he was professional in every way. I hope this new unit gives the service and longevity of the old one. We will see. From my experience with Precision Overhead Garage Door Service and Alex, I would use them again and I recommend them.read more
