How to create the concrete footings using embedded post anchors for an arbour?

[BeginnerPaul]

Good Evening Folks

I would like to construct a small arbour say 2metres by 3 metres and 2 metres high. Posts say 90x90

This question is about creating the right footings for the post anchors

Am considering post anchors which will be embedded in concrete

Pryda 200 x 90mm M10 Full Stirrup Solid Stem Post ...$16.31Add to Cart

Question is what are the right dimensions for the concreted hole which will have the post holders embedded

All advice welcome

Hi @BeginnerPaul,

Yes, the bit included in your Bremick XTP 14g x 150mm T40 Stainless Steel 316 Bugle Batten Screws will be a driver bit.

There's not a huge amount of difference between driver bits, but these IRWIN 75mm T20 Magnetic Power Bits are good quality and magnetic so they should be a good option for you.

Extension bars such as this Kango Hypertorque 300mm Impact Extension Bar can be handy if you need to drive screws that are just out of reach, but realistically with your project, there is not much need. Moving your ladder and body so you are balanced and comfortable will driving screws is always better than using an extension bar.

Let me know if you have any further questions.
