I need a fairly heavy poster cabinet wall mounting on my upstairs landing(regular floor beside, no access problems), however a steel backing piece which should fit will need bracket/flat plates(joining plates) securing between cabinet and steel sheet first , I don't have those joining plates.(It did have a cardlike ribbed plastic backing held by those tiny metal tabs, and those tiny metal tabs won't be satisfactory). I DO have the wallmounting bits that came with the cabinet but because of the extra weight may need more holdings in place, drilling. I do have more jobs that I will need doing, bigger than this but I have decided to advertise 1 at a time. Hopefully you live nearby in Hull because I am no expert on what would be required, diyer wise, so as with a regular quote where a person gets to look at whats required done first, it may need a recce first, (I can't see a problem if you are a regular DIY industry worker, IE regularly has need to visit a DIY shop and knows the bits and bobs), I have included that for my price estimate, IE no surprises me or you please.
