Question on Pryda Stirrup Post

[ozfreelancer]

Hi,

I have to fix a 90mmx90m bearer to a Stirrup POst. I bought the 90mmx300mm Pryda Stirrup Post. Now when I place the timber bearer flush with the top of the post holder, there is a gap of about 20mm or so at the bottom. I mean the 90x90 bearer does not sit on the post. I have atatched a picture to show this. Is it OK to leave this gap or should I place an offcut to block this gap. Similarly there is a gap on the side too but of only 5mm or so.

ANother question, when I have hole of 600mm deep, how big the stirrup post should be. I mean I can get 90mm stirrup post holder that have 300mm, 450mm or 600mm long stem at the bottom. WHich is the right one to use ?

Thanks for all the help and advice


Cheers

Is it possible that the stirrup is 100mm? If the stirrup protrudes above the bearer, and doesn't get in the way of anything else, it could be left that way.

If it does get in the way, you can pack under it with some cement sheet to raise the bearer. You could pack the side as well, but it will probably close up ok when you bolt it.

I would work the length out so you have at least 200mm of concrete under the lowest point of the stirrup.

Thanks a lot.

The Stirrup posts are 90mm. Or atleast that is what the product code says which is barcoded on it which is PSFS30090. And according to the Pryda catalogue this is the correct one for 90mm posts. I have the cement sheetings that they use under the eaves of houses. Could I use that to pack it up ?

I can't let the top protrude becasue in that case I can't fix the second M10 bolt through as part of the bolt hole will be outside the timber.

I have the cement sheetings that they use under the eaves of houses. Could I use that to pack it up ? That's the sort of thing I mean, however depending on the age of the house it may contain asbestos.

If you only need a little bit, you could probably get some cement sheet from a Hardware store, off a broken or packing sheet. You can still pack it with wood as you suggested also.

I assume this is for a deck. There is probably no need to pack. There are several examples here where people have done this without packing including myself.

See;

or

http://www.renovateforum.com/f196/easter-long-week-end-project-backyard-deck-75961/

There are other examples as well.

Packing won't hurt, but I'd suggest not necessarily required.

if the gap is 20mm or so I would think that an off cut of your decking would do fine as a packing material. It should be 19 mm or more, so if that works that is what i would most likely use.

As for the stirups yes they are probably for a 90 mm post, but that is a post, upright and therefore it does not matter if the metal sides are 110 - 120 mm in that aplication.

Have fun

check the internal measurement , should be 92 mm wide , if not it has probably been mislabelled or as often happens with Bunnings been put on the wrong shelf
