Gas N Pow3rConcealed Shelf Supports Brackets 120mm Floating Hidden Masonary Fix HEAVY DUTY x4

Used these to install a 2m long 200 x 100 oak mantle - set these at approx 30 centres and they've worked a treat.The fine ajustment via the off set centres really helps to line up multiple brackets.: I had 7 of them (probably OTT..!) lined up and I think it would have been v tricky without this function.Good product

Super fixing for blind shelf supports. Offset thread allows for slight adjustment of alignment.Points to watch1. The wall needs to be masonry and not a stud .2. The masonry bit needs to be 10mm to secure the wall plug.3.The shelf needs to be drilled 12 / 12.5 mm4. Critical that shelf is drilled square, central and is of a minimum thickness of 25mm width5.Make a metal template for hole alignment on both shelf and wall ( metal banding is ideal )6.Pilot drill all holes with a 6mm wood and masonry bit using a template.The offset can be used for minor aligmnet adjustments

These are simple and the off-centre adjustment is useful to get things perfectly level. You need a narrow gauge spanner to make the adjustments, otherwise you'll be gripping with pliers just to get the screws into the wall.The wall plugs supplied are okay, maybe a bit on the flimsy side. I'm a novice DIYer so if I did this again I'd throw in some bonding before inserting the wall plug just to remove any extra play in the shelves. The system is solid, but there *is* a small amount of play. Still, you'll know the shelves aren't going anywhere as the torque required to get the screws into the back of the fixings is massive.

I used these for long shelves, 3m, so needed 7 at 450mm intervals. This meant getting the hole positions in the wall accurate, the eccentric feature gives just that little bit of leeway. You then have to accurately drill the holes in the shelf to match. I countersunk these holes slightly and put some vaseline on the bolts and the holes in the shelf to help the shelf slide onto them. The shelf is now full of books and has stayed in place.Good product, requires careful fitting.

Got these to mount a long cut off from my new kitchen countertop. Makes a good sturdy shelf in the hall now and looks great. You can use them to make a shelf to any size within reason. Great when you can find the size or look of a ready made one.

The turn function, to be able to straighten them up is novel and actually a hinderance. It dumbfounded us for a while, why not just create them straight! I have attached a sleeper to the wall, pack of 4, two was enought for the job, but I wouldn't buy or want to faff that much ever again.

If you want to make your own floating shelf these are ideal. Drill holes in shelf, insert brackets then mark wall, checking level. Remove brackets, drill and plug holes and screw in brackets. Then shelf slots on. If you’ve gone a bit wonky there’s a little adjustment as crew is slightly offset.

These are great and can be slightly adjusted when on the wall by spanner to get perfect level..only down side for me was my shelf already came with pre drilled holes that were too big so shelf was a little wobbly. I managed to get around this by putting locating screws in the shelf to hold shelf to the brackets. If I had drilled holes myself then they would have been snug and perfect as long as you get the hole straight ideally use press drill. Good quality, sturdy and comes with good fixings for masonry wall.
