For all the various models we offer online the easiest roller doors for installation are these:
Gliderol Series A and B Single skin steel roller doors - a very basic single skin roller door which is very forgiving if your garage opening is out of square. They only fit to the inside face of the garage opening which is the easiest place to fit any roller door anyway.
GDO ROLL 77 - The wall button and key switch electric operated ROLL 77 roller doors have the simplest installation set up with no remote controls or obstacle detection systems to set up.
Hormann Rollmatic II - External electric drive and the curtain is delivered ready to attach and lift out of its transport casing. An easier roller door to set up and with the external motor the setting of the limits is easy.
Most of the electric roller doors we offer online have been chosen for their high quality but also because they have a logical installation process and we find the lowest levels of issues in after sales with them. This is after 17 years of trialling and tweaking the models offered.
