Use of dead spaceMary J.This really help me to utilize a corner that otherwise would have been dead space5
Bought for future useCarol M.Waiting for the skinny Billy Bookshelves to come back in stock at the IKEA closest to our home. Spotted these adapters to connect bookshelves in a corner configuration. Three sets were in stock figured I better get them now and hope the the skinny Billy shelves come in soon. My art studio is on hold while waiting. Hope this product works as expected.4
Angle braces for multiple bookshelvesCRAIGCould you offer the brackets in colors that match the bookcases? Could you design crossbraces to attach to the rear of the bookcases as both distance maintainer and a reinforcement (from the back of one bookcase to the back of the adjacent one to maintain distance and add strength to the connected structure (anti-tipping for center, angled unit)5
Love love billy shelvesLeonard01Would recommend these to anyone who needs shelves. Very easy to put together and look great!!5
Exactly what we needed toFloyceExactly what we needed to make a tidy corner library unit. The units are all flush and it's seamless.5
Great Product10RNotesSuper easy to use. Makes putting in a corner unit a breeze.5
Secures the bookcase wellcdletgoThe shelves look great. The corner hardware holds it all together for an even, uniform appearance. We had a little difficulty adding the extenders on top.4
Easy enough for one to do!LindaLovesIKEAI had a friend help me put the 5 bookcases together, but it was up to me to put them in place and add the corner hardware. I was able to do it myself and I'm a 60 year old lady with some disabilities. If your floor is uneven, like mine, you may need to use shims to even them or put up with the pieces not matching up perfectly.5
Billy Corner hardware disasterNik GBought these, but couldn't make them work correctly.1
Just right28929I got two of these for two corner units in my library. They work great and are very secure and easy to install. I would make two little changes though. First, I would list on the web site the distance that you have to give from the wall to the next bookcase (23 inches). This is mentioned on the product sheet in the store but I like to do a lot of my planning at home online. Second, I would have changed the screws for the top into flat head screws to present a lower profile. My ceiling is not quite as tall as is allowed by the extensions so I have cut the extensions down and in order to let them lie as flat as possible on the shelves I've had to find some spare screws that work better.4

Function solution

Use the corner

BILLY corner fittings make it easy to build a corner solution using the classic bookcase. Start by putting a 15 3/4" wide shelf in the corner. The fittings will help you to put the shelves at the right angle and make the solution both tight and stable.


What is steel?

Steel has unique characteristics when it is stretched and shaped since it remains strong. It provides strength to everything from skyscrapers and cars to bed frames and outdoor furniture. The steel industry is moving in the direction of more energy-efficient production and stronger steel qualities. It doesn’t lose any of its properties when recycled and today steel is one of the most recycled materials in the world.
