Heavy Mirrors

Gripit fixings are solid for heavier items.

Depending on size of mirror and preference of where it is placed, I would suggest that you find out where one or two of the joists are behind the plaster board and use a least 50mm or 60mm wood screws, if no joist can be found, a butter fly plaster board fixing will do, but if the mirror is over 5 kg and no joist can be found, I would suggest having a noggin but in behind the plaster board for getting a fixing

Molly bolts would recommend

On Screwfix they sell amazing fitting called grip it 172ja 116kg they can hold up to

Plasteboard fails at 8Kg - 10Kg per fixing, regardless of the fixing you use, it is the plasteboard that breaks, not the fixing, and you cannot increase the strength signficantly of plasteboard by using a more expensive fixing - this is a fact. And so go by this rule - 2 screws - safe load 8KG (half of the limit), or 16 KG is the point that it will break. There are 4 types of plasterboard walls however - ones supported by Wood or metal studs, one with concrete immediately behind, and then ones with plywood to support weight (this is in newer builds in the living room area only). Attaching to studs or concrete will give you a MUCH stronger fix. You also get plasterboard walls with thicker plasterboard, these hold upto 3 times the load mentioned above. Hope this helps, take it from a tradesman that has NEVER had a TV come off the wall and I’ve put upto 85 inch TVs onto the weakest plasterboard.

GripIt from screwfix is the solution to anything heavy and plasterboard.

Imo I cant fault the simple easyfix spring toggles, cheap and cheerful from screwfix and withstand just as much as any other brand, as long as you take into account and understand that no matter how good the cavity fixing it'll be the plasterboard itself that will fail first, plasterboard could fail on a single fixing under just 15kg depending, and if on an older damp wall, much less, finding a stud is always the strongest even if not central but if not, spring fix with spacing between!

It's depend on wait...first step better to find wood and see in an alone any socket or any other thing goes make 40 mm pz2 adapter screw..or easy fix hollow plugs is second gd option for it...

Using gripit is the best
