Question: how far apart are the lower bolt holes?  24" on center, I hope?
Document: It does the job, looks great, and is very sturdy. The key is obviously in how well it's mounted, as the instructions make clear. I have the rear mounts, which are 16&#34; apart to line up with standard-spaced wall studs, in studs using the included lag bolts. The holes are big enough to allow some wiggle room, which is nice and also lets you fine tune to ensure that it's level.
This is a very nice rack. Solidly built, nice finish, and the half circle shape looks nice.A quick note about mounting this. A previous reviewer said it is not possible to mount this on wall studs. This is only partially correct. This rack has three holes: two on the half circle, and one on the middle bar (the part that extends vertically). The two holes on the circle are spaced exactly 16 inches apart- this is the correct spacing for wall studs.
Everything feels very sturdy this way.A couple notes:The instructions say drill a 3/8&#34; hole in the drywall for this particular toggle bolt. Good luck getting it through that size hole. I had to drill 1/2&#34; and then pound the bolt/anchor through with a hammer. Maybe they changed hardware but did not update the instructions?The included hex nut DID NOT fit the center bracket bolt.
I ended up mounting the top bar into a centered stud and the bottom half circles in 2 places using &#34;butterfly&#34; dry wall anchors. So far so good.
This rack is sturdy yet does not make the kitchen look too busy if you have limited kitchen space. So far, it's holding up our copper pots/pans.
I looked at many, many pot racks before finally deciding on this one. The most important aspect was quality. I needed something that would be sturdy enough to hold about 75-100 lbs. I wanted something that would be easy to adhere to the wall (and not fall off or rip apart my wall!). Lastly, I didn't want to spend an arm and a leg for something beautiful, but didn't work well.I'm so happy!
This is an attractive pot rack; however I had to make several visits to the hardware store to find the correct size nut for the bolt that's inside the rack. A nut was provided, but it's a standard 3/8&#34; nut (although the directions say it's 1/2&#34;) and the bolt on the rack is metric.
I assumed the nut was poorly machined and would thread on with some effort, but upon examination it appeared that the threads were finer than the bolt, no match. I was taken aback that a seemingly quality product could have such a glaring oversight. Not sure if I just got unlucky (no other review mentions this) or if there's a bad batch out there. Luckily I was able to rummage around my spare parts bin and find a nut with the correct threading, which proved the issue.
I bought this pot rack from amazon instead of bed bath and beyond bc i wanted the stainless steel version.. when I got it home and unpacked it the nut would not screw onto the bolt.Not one, but two trips to home depot later, there was nothing that could be done. They said that the bolt was missing tread at the top and therefore it was a manufacturer error.I still really want this pot rack to work out but it's super discouraging.
The package comes with all the hardware you need to install, 3 lag bolts and a 3/16" toggle bolt (in case you can't find 3 studs in the right places). I purchased my own toggle bolts after reading other reviews, but it turns out I didn't even need it. It feels sturdy enough to easily hold the weight of 6 pans (I have two 12" skillets, two 10" skillets, and two large saute pans hanging on mine).
Answer: As answered before, they are 16" centers. However, since you have 24" center wall studs, I would just find a nice piece of wood and mount it to the studs as a ledger board and mount the rack to that. It will be super strong without straining any drywall. Could finish nicely or just make it narrow and almost totally hide it
