Very good, stable door

Have about 4 hours to assemble hand (1 hour for special work, because I've read points). One should really adhere strictly to the instructions and read point by point exactly, then it should be no problem to build the door properly together.
The door is very stable. Screwed (holes must be drilled with drill guides itself, but is not a problem - even the drill is) are cross bars top and bottom, center crossbar and longitudinal beams placed with broad hard plastic connectors.
Had previously bought from the hardware store to a door a few more Euros, which has held only a few days, because the plastic connectors are broken.
