2 Pcs 711 Bed Frame Bolt On to Hook On Conversion Brackets for Headboard with Hardware, Adjustable Bed Rail Hook Plate Adapter，Hook on Bed Rails Brackets

Used these to add a new bed frame to an older frame. These worked perfectly! Very sturdy and solid.

I had a metal bed frame that I was attaching a headboard to that was originally attached to a wooden bed frame. So this worked perfect for the attachment.

A simple diagram would have saved me some trial-and-error and google searching but it's not actually HARD to install. I just didn't find it intuitive and it didn't come with any documentation. I'm happy to have my headboard attached to the bed frame, and it seems sturdy.

My bad Did not measure properly so they did not fit. But they looked sturdy and strong.

Bought a headboard but not the footboard and wanted to attach a metal frame for a queen mattress. I did not want to drill holes in the headboard, which had the usual mortises to receive bedrail hooks. I didn’t know this sort of hardware existed until I did a Google search. Not available at local hardware store. This hardware arrived quickly, was easy to install, and provides a sturdy connection.

We have a Stanley furniture sleigh bed and decided to buy a Tempur-Pedic bed, with Ergo base. We had to purchase the tempurpedic brackets, but with those brackets and these, I was able to secure the original headboard to the tempurpedic ergo base. Fits well and very little movement.

All I can say is that I should have went with the Ronin factory bed bracket set. These were slightly wide enough to have to beat them into position with a hammer. The screws for mounting were such a joke, the first one actually broke off leaving a stub in the hole. And so short you couldn’t possibly get it to bite properly into the wood. Do yourself a favor and spend the extra money on a quality no hassle product. These things suck.

Used to connect an antique headboard to a modern steel mattress frame. Be aware: The height of the frame must be adjusted such that the weight of the mattress & frame is borne by the headboard. i.e. the headboard cannot "float" suspended on the frame but must touch the floor. Otherwise, the hooks will lift out of the headboard slots. Typically, these adapters need to be used with an auxiliary plate which has adjustable slots to assure the mattress weight sits on the ground.
