Well to start with,who ever desnged the door whats to go back to enginering collage! If I emplyed him/her they would be SACKED, total rubbish!!
No locking system,no chance of anywere to fit one,
and the top roller system`s too small and the bottom atachment is so small and flimsy it relyes on a tiny pice of plastic 4 mm to hold the bottom of the door fron dislodging it`s a joke.
My new( 6 week old) Halls popular 8x6 is in a very sheltered place from north , south east and west yet the door managed to unhook its self and smash all the glass.The door assembly is what can only be disscribed as CHEAP &NASTY. Come on Halls get a grip and make your Halls popular fit for purpose,as they are they are quite cheap and flimsy
