Like others have mentioned, the Franke Grids can be covered with a clear plastic. Over time the plastic gets filthy. That happened to ours so I ordered this one that is not covered with the plastic. Unfortunately the new grid without plastic was much larger than the one we have.Instead of trying to find the right size I decided to try to strip the plastic off our grid. It turns out that while it does take some time to do it, it's not difficult to peel the plastic off (use a box knife blade to split it and then pull to peel it back). And when you do you will find that underneath is a gleaming, shiny stainless steel rack under that plastic. So you might give that a try if you can't get the right size or if you don't want to spend a small fortune on a new one.Hope this helps someone out,JimFit just like the original rack except for one thing the rack did not sit in the sink properly as another buyer indicated the problem was the center set of legs had one leg longer that it should have been the culprit was the front one closest to the drain I removed the pad and ground off 3/16 in off and reassembled problem solvedI was concerned about the review that said it didn't fit, but it fits my Orca sink perfectly. It is twice as sturdy as the original and the bare stainless is way better than the plastic coated one that attracted mold like a magnet.We purchased the Franke ORX 110 stainless sink for our kitchen remodel six years ago. We also purchased all of the accessories such as the grid drainers, cutting board, tray. The drainers were the coated ones which we figured to be better than plain stainless, providing a cushion between dishes and the steel rack. Within a few years, however, the coating started to wear on the bottom drain, and the metal developed a corrosive look. We decided the best option was to purchase a new bottom grid, electing to go with the pure stainless one this time.Our original purchase was on-line from WSC Direct. We searched the web and found that the one on Amazon from East Coast Plumbing Supply was the best price. We received it today in perfect condition in the factory box. I am extremely pleased that we went with the stainless version for the bottom grid. It weighs more than the coated version and I'm sure it will be easier to keep clean. Have no complaints and highly recommend East Coast Plumbing Supply.lf you need this grid to fit into your Franke sink (and if you do there's no other grid that fits as precisely), get this model and not the coated version. They are not cheap, as you can see. But the coated version, which we bought with the sink, quickly discolored and became unsightly. It even peeled in many areas. We thought perhaps they made a mistake and the coating was supposed to come off. We were the ones who actually us that made the mistake by buying it in the first place. Had a know then what I know now, I would have bought this one, which was probably not available. It fits the sink just perfectly and I recommend it so far. The construction is nice and thick, too. Perfect for this sink. I'm only sorry we wasted $136 on the first one and there's no way to contact Franke.Over all a beautiful product works as designed ... Provided you have the newer style ORCA sink.In our situation this didn't work as the center leg support closest to the DRAIN was to long ( .5 CM) causing the rack to WOBBLE when any plate pan or glass etc was placed on top of the wire frame.This happened twice on two units - the original and the replacement sent from AMAZON.Our FRANKE Orca is a vintage from 2009 the earlier version, FRANKE has made a slight change in the stamping process - from what I can see is the FRANKE changed the slope of the sink bottom close to the drain - to increase water runoff towards the drain. Which would be why this center leg is longer by .5CM:Thanks to Amazon for prompt replacement of the first unit and also prompt return of the 2nd unit.FRANKE support in TN was very helpful w finding a replacement unit that fit the sink like it was new.The support person stated that this had happened twice before to him and was able to resolve the issue.If you have one of the earlier versions of SINK GRID for the ORCA sink this could be a problem, our GRID came originally as a grid w vinyl coated wires and the new one is not that way. This was a question that the support person asked which I assume allowed him to figure out the problem.Anyways we are all happy now w the new insert.I purchased this to replace one that I purchased ten years ago. This new version fits perfectly and is constructed with better material.Love my Orca sink and love these grids - keeps the sink looking great. Would also recommend getting the side rack. The UNCOATED grids are much better than the coated ones (which I previously had). The coated ones are harder to keep clean. Warning about this rack though: when you take it out of the box, leave the plastic 'tubes' that are on some of the perimeter grids. I thought they were just to protect during shipping, but they are actually to protect your sink! (oops, yes, I did throw away one one them before I figured that out).Unfortunately, the product we received was not as advertised. The dimension of the product we received do not match the Franke OC-31S-RH grid. What we received is a totally different size.exactly what i needed for my Franke sink. Much cheaper than from retail dealer. Very strong and attractive.appreciate that it included the sink protectors as shownGood product well packaged.Great.
