Fixing a 17kg Bathroom cabinet to a dryline (dot and dab) wall

[RubbishAtDIY]

Hi guys,

I have the following cabinet which I need to attach to a dot and dab wall (single course of brick -> gap -> plasterboard/plaster.

http://www.ikea.com/gb/en/catalog/products/70217671/

The cabinet is 17kg in weight and has in both top corners points to attach the item to the wall.
At the back of cabinet is a 1cm gap between the wall and these points.

I am considering using a screw of length 90mm with a dryline pro (http://www.drylinepro.com/DrylinePro-Products/8-Fixing-Kit.html)

10mm for cabinet/wall gap, assuming around 10mm for gap and 70mm into the brick (these are on average around 100mm thick??)

Does this seem sensible?

Should be fine assuming it's not insulated plasterboard.

Did this drylinepro product work for you for this cabinet? I am in similar position, so your feedback would be greatly appreciated. Thanks.
