Very satisfied
Works great. Extended the width of the footboard so the mattress finally lays flat. Couldn't be happier with this solution to my problem.

Rockler headboard adapter
Purchased the headboard adapter plates after buying an antique full sized headboard. Took all of 10 minutes. Attached the plates to my queen bed frame. Marked where the new headboard would be attached and used a 5/16 drill bit for the holes. Used 1/4 in bolts. You just need to determine the length of the bolts depending on the thickness of the headboard legs. Highly recommend!

It didn't appear that you had a proper solution (one that utilized the pins already found in the bedset legs) so I went with what appeared to be the next best option.

we installed the conversion plates to make our full frame into a queen. There is so much wobble we cannot use it. and yes the bolts are tight. How should we stablize the frame?

I have an antique bed frame that doesn't fit modern sizes. I use a full-sized mattrest and just the headboard right now. Is there something similar that would work with hooks instead of bolts?
A shopper on Apr 28, 2015
BEST ANSWER: Sorry no, we do not have any similar brackets to offer for use with hooks.
Will this product accommodate 5/16" bolts, or only 1/4" bolt?
Barb B on Aug 23, 2015
BEST ANSWER: Only 1/4 "
I'm looking for a double hook on mechanism that can be used for a full size bed and a queen size bed. Both parts have to be hook on. Any thoughts?
bobbi k on Dec 4, 2016
BEST ANSWER: Debbi, I used to work in the bedding industry, and I have also purchased the double hook-on mechanism for my daughter's bed. Let me say that there are places that sell the frames with the hooks already welded on. The Rockler people can let you know if they have such an item. If that would work with your situation, I'd recommend doing that. The adapters are very difficult to tighten and keep hooked into your headboard/footboard.
My bed has hook on wood side rails. Can I use these?
Susan M on Jul 28, 2017
BEST ANSWER: No, you will need to buy a queen size metal frame, with headboard and foot board attachment points.

Your headboard and foot board become ornamental, not structural.
Can I lower the height on a king metal bed.? ..
A shopper on May 2, 2015
BEST ANSWER: You should be able to do so, simply drill new attachment holes below the level of the present ones.
Can the conversion plates be reversed so that my queen size headboard can be attached to my full
size frame?
Kyle H on Aug 26, 2017
BEST ANSWER: Yes that's why I bought them for the same exact reason!
I am looking to use a 3/4 antique head and footboard with twin size mattresses. Will this work?
Erin R on Jul 1, 2016
BEST ANSWER: If the side rails are intended to bolt to the headboard then yes. If the side rails have tabs that fit into slots in the headboard the answer is no.
Will this adapter work to attach a full size brass headboard to a queen size bedframe w/mattress?
Nita O on Jan 30, 2017
BEST ANSWER: If your brass headboard has round legs it definitely will not work. a full size bed is 54" wide vs a queen at 60". Each bracket would need to cover an extra 3 inches. I would recommend attaching a 1"x 4" across the top of the queen frame, then fasten this to the brass headboard. Also I would make sure that your frame has 4 legs so that the weight is properly supported as well.
How does these brackets make bed longer?
Elsie D on Sep 30, 2016
BEST ANSWER: Hi Elsie, The brackets do not make the bed longer. If you are using them to make a queen out of a double, the length is the same for a queen and double. A queen is only 6" wider than a double (3" on each side) so you don't even notice that the headboard is not as wide as the mattress. A king size bed is 72" wide, while a queen is 60". These brackets would not work very well I don't think. Hope this helps.
Is it possible to convert a twin size headboard into a queen size using your attachment pieces. My daughter is buying a quee. Size bed but doesn’t have the money for a whole furniture set so we were wondering if we can use what she has and just use the attachment pieces to make it larger?!
Mary C on Aug 25, 2018
BEST ANSWER: Adapter 32236 is made to go from Full to Queen which is a change of 7 inches in total width. Adapting from Twin to Queen is a change of over 20 inches and that will not work with these adapters. Also, there might be an appearance problem with such a combination.
What purpose does the embossed "X" in the middle of the plate serve? Your diagram shows the raised part of the X away from the wooden frame. Other installer appears to have the raised X next to the wooden frame. Directions on plate says "this side to frame"...that is the recessed X side. What frame?....the headboard frame? or the metal rail frame?...kind of sort of confusing?
don B on Aug 21, 2018
BEST ANSWER: I purchased this kit of bed frame extensions. As far as I can tell, the embossed “X” on one side of the extenders is just to help you keep all sides of the extenders on either the inside or outside of the bed frame as you assemble the expanded or shortened bed. Just a courtesy to prevent you from assembling the new bed and finding out that you have installed one corner incorrectly.
Will this work with no bolt side rails?
Jacqueline N on Mar 17, 2018
BEST ANSWER: I don’t think so. The plates are made to bolt to the headboard and then you bolt the bedframe to the plates. We comverted a full size bed to a queen size and they worked great, but again we had bolt holes for the frame and headboard.
I have a queen size wooden frame bed(headboard, footboard, and side rails). Is there a bracket that can help me convert it for the use a full size box spring and mattress set?
Marina G on Mar 16, 2017
BEST ANSWER: These brackets are designed to make a headboard/footboard wider. I don't know if they will work to make a queen headboard/footboard narrower to accommodate a full size mattress. Most people seem to want to make a full size bed into a queen size bed, not the other way around!
Can I use these extenders I have queen wanted to make it king ?
Kim S on Oct 22, 2016
BEST ANSWER: Doubt it, they do not extend that wide. Also, bc they hit so low on the headboard, it makes your headboard a little wobbly, but it did the trick for us when we couldn't use our existing bed rails.
Will I have to drill holes in my bed or are one side of the plates have the hooks that go into the legs?
John B on Aug 18, 2016
BEST ANSWER: I used the adaptors to convert a double bed headboard for a queen size bed. I did not have to drill any holes in anything. The adaptor provides plenty of wiggle room to fit the rails. However I just attached the headboard to a "harvard" bed frame and did not use the side rails or foot board. I've recommended these adaptors to several antique shops in my area that have many double bed frames for sale that no one wants. I have referred the Rockler website to the dealers.
If I install these adaptor plates on the head and foot board of my full size bed, since the queen size mattress and spring are about 5 inches longer than a full size, will I need different bed rails for the queen size?
James B on Aug 21, 2018
BEST ANSWER: YES
My headboard is wider than my metal bed frame. There are 62 inches between the slots on the headboard and the bed frame is about 58 inches wide. Will these adaptors work?
Mike D on Jul 18, 2018
BEST ANSWER: I think these adapters will work for you. There is at least a 2" "give" on each adapter. My headboard is 3-4 inches narrower than the bed frame and these worked like a charm.

pam a on Oct 10, 2017
BEST ANSWER: No, cal kings are just longer.
Can I still use the wooden side rails? Show me how this works
Judy P on Aug 15, 2017
BEST ANSWER: This product is designed to relocate the bolt holes in the head and foot boards outward to accomodate a larger matress. If your side rails BOLT onto the head and foot boards, the product illustration shows you what you need to do. If the rails use hooks to connect, this product alone will not solve your problem.
Can this be used to adapt a hook-on full headboard to a bolt on bed frame?
Grace L on Jun 15, 2017
BEST ANSWER: Not sure what you mean by a "hook on" headboard. The picture is very self-explanatory as to how the extension works with bolts.
I have a full size sleigh bed that I want to used a queen mattress do you have any products for this type of conversion? My bed rails are hook on and side rails are wooden.
Kendrick M on May 13, 2017
BEST ANSWER: We don't have any products that could connect to a hook on the rail. Sorry
