Yes, in fact the intial price displayed above is for the wall mount version, this is standard for of any of the Fold Down type clotheslines. To have it ground mounted like in the first image above you will need to add the Ground Mount Kit option to your order, this option is located on the right below the price displayed above.
This is the type of post kit that you will need if you are installing the posts into a grass/soil area in the back yard. It is 2 x Posts(approx. 2370mm long) and 1 x Rear Spreader Bar. This is the most common type of post kit and if you scroll through the images above you will see what the Standard Kit looks like.
A Plated Kit allows you to bolt the posts down onto an existing concrete area rather than core drilling or jack hammering holes into the concrete. The posts have metal plates welded on the bottom with holes for dyna-bolting down onto the concrete. It is 2 x Posts(approx. 1865mm long) and 1 x Rear Spreader Bar. If you scroll through the images above you will see what the Plated Kit looks like.
Yes you can but you will just need to make sure the mounting brackets align with the timber studs in the wall. If not you may be able to customise the width of the clothesline(see 1st question above) to suit the studs. The alternative is to purchase the optional Ground Mount Kit with the clothesline and install it freestanding in front of the wall.
A general rule of thumb is to install the top bolt of the fixing bracket at approx. 50mm above the users head height. An average height is approx. 1.8m(1800mm) but you can adjust this to suit your requirements, just keep in mind the Addaline 35 has a depth of 1.5m(1500mm) so the height has to be anything over this so that when it is folded down the frame won't hit the ground.
