Question: my wall mount is 15 years old, I can't find a fit for it.11x42 it has a square end where it mounts to the wall.
Document: This is perfect fit for my in wall ironing board, a very hard item to find. It is exactly as advertised
Fit perfectly for my 20yr old Ironing Center. If your board has the flat end this is the one to get.
My ironing board is 14 years old and the cover was falling apart. After I researched the new model number (the old number no longer existed) I ordered it. Was I ever surprised. Not only did it I get it in a timely fashion but it fit perfectly. Infact it fits better than the old one. I'm so happy with it that I almost like ironing - almost. No, that's a lie. I just like the cover.
This cover is exactly as advertised. It came promptly and fit nicely on my ironing board. Being able to find it online was great because I have no idea where I would find this locally.
The cover was not made like the old one and it was too small to fit the board correctly. Not satisified with this product. I would not order this again.
I would not reccommend the product. It doesn't fit and is pretty cheaply made. I put the old on back on. Infinitely a better product.
I needed this and was glad to find it but it won't stay on like the nutone cover did. Blah blah blah blah blah
If you do not have straps with fasteners, I would advise purchasing some with this item. It does not fit snugly on its own even though it has one strap in the middle.
This cover does not fit like the original. I did manage to get it on but the cover is not long enough so it flaps around in the ironing center. It doesn;t interfere with ironing but does make shutting the door difficult as the board doesnt lie as flat.
After purchasing and returning another cover from a local hardware store (which was supposed to fit, but didn't), I was skeptical about ordering this one. However, it fits snugly, but it does fit and as mentioned in previous reviews, the Velcro straps really help. It also has a nice finish on it. Would certainly purchase this again!
Answer: Our board is 12"x42" and the cover I purchased fits it well. Not sure if it would also fit your 11" wide board.
