concealed stair tread hardware

I’ve never come across anything hardware specific like that before. Not saying it doesn’t exist, but I’d be pretty surprised if it did.
Hard to say what they’ve done in the picture….some kind of a metal french cleat maybe? Doesn’t look very good whatever it is.

Is this for a new house or a reno?

Thanks for your response Tony. I can’t answer your until I can talk to the person doing this. A friend of mine sent the following email so I basically asking the question for him. My guess is this is a redo or new in an existing house.

Hello Richard,
I’m looking for these stair treat brackets. Any ideas?
I suppose they could be a stainless angle that is concealed by a dado cut in the end of the tread. I see a simpson staircase angle that might be it.

I’ll post any new information I get.

Last time I had to order from Stairsupplies.com but I had to call to get what I wanted. Actually i think i used the contact form on their website and they called me. It was hard to find on their site.

it looks they used the simpson brackets which dont really hide very well.dont know about what your looking for though.

Looking closely, I’d have to agree with Tony, doesn’t look too good. I suppose it would be fine if it was expected the ends were going to be trimmed out with something to cover it but the modern, sleek look doesn’t lend itself to well to such an approach. I’d use angle lagged to the studs and buried in the ends of nice chunky treads.

Unfortunately there isn’t a close up photo. It looks like the brackets are attached on top of the drywall which could loosen up over a period of time. More photos of the job site would be helpful showing what the brackets are being attached to. I have never attached a thread in this manner, but an aluminum Z clip may work if they are attached to a solid surface. The Z Clips that I use are about 3” wide and come in 20’ lengths without holes and are fairly thick, probably 1/8”. Contact an aluminum distributor until you find the wide ones. I would also make the treads in several sections and attach them individually not in one piece. This would give you more control to get a perfect fit. Below are two links showing Z clips. Is the staircase going to be inspected ???
