Roller garage door on 9 inch cavity block shed?

paddy147

Hi there,quick question for you.

Can a roller garage door be safely bolted/fitted up onto a 9 inch cavity block shed??

Does the part of the shed wall (where the actual roller dooor mechanism is going to be fitted up above the opening) need to be strengthened in any way with different style of blocks or bricks,or will 9 inch cavity blocks be able to hold it in place??

Thanks.:)

Perhaps the supplier of the roller has a standard detail? If not, ask a structural engineer.

Any builders of competant DIYers here not able to answer this for me??

Can I bolt the roller door mechanism straight into 9 inch cavity block over the opening??

only the two vertical guides need to be bolted to the walls, and in most cases because the opening is quite wide a 9"solid head would be above the opening, which would be a secure anchor point.
as the holes are not pre determined in these guides, you can offer them up to the jambs and mark your solid points on the block work, i.e. an inch down from your bed of mortar, as up would be thru the small upstand on the block.
in most cases it is only five 10mm rawl bolts on either side,
does this help or make sense ??

quite a rant untill it was deleted, its a garage door not a suspension bridge,

They are generally fitted without issue to hollow block sheds. If you are just building the shed now, you could always use 4" block on flat in the area around the opening but it would be overkill to be honest

Thanks to Fester Beatty for that long winded and rant of a post.Why,I dont know.

And thanks to every one else for the good/decent and helpfull advice.:)

Poor Uncle Tom

Actually, FesterBeatty is right, without all the facts your question is meaningless. Structural issues are not to be discussed here, it is a breach of the charter.

Itsnt it funny then that both Martin and Mick answered my question for me then.

Thanks to both of them.:)
