Your cart is empty.The FST2 tool straightens commonplace 16, 18, 20, or 22 fins per inch. The tool features one-piece adjustable combs. The resilient nylon comb material will not damage the soft aluminum fins of condenser or evaporator units. Malco fin tools function by either pushing or pulling and efficiently straighten fins in tight quarters or where multiple passes over bent fins are required. Comfortable offset handles provide a sure grip and protect knuckles from scraping.

Definitely not worth $50, wouldn’t even pay $10 if I knew how it was actually made

It works. It would be better if the spacers weren't plastic, but it did the job.

Garbage just garbage. Poor quality, thought it was metal and it actually damaged fins even more.

I initially tried a metal fin straightening tool from Lowe’s (also sold under different brands on Amazon), but it was a total disappointment. Within five minutes of use, it fell apart. The small wire pieces meant to straighten the fins kept getting misaligned, and it was clear that the metal pieces weren’t properly crimped. I returned it as defective and decided to do more research before trying another tool.I came across this new tool and watched a few YouTube tutorials, which was crucial. A tip I found helpful was to avoid forcing the fins. Instead, gently slide the tool up and down in both directions, taking your time. Be patient on damaged/bent fins and work from the edges toward the center, focusing on one section at a time rather than diving straight into the middle of the bent fins. If you encounter resistance, don’t push too hard as you might tear the fins. If the tool doesn’t go through in one direction, try approaching the fin from the opposite side. Sometimes a damaged fin can block your progress, but by alternating directions, you can straighten everything up to that damaged point.This tool worked much better for me, and with a little patience and technique, it got the job done without causing further damage to the unit.I attached a photo with before and after pictures. The before pictures are on top and the after pictures are on the bottom.

I had an air conditioner (a/c) with mashed in fins that needed straightened. This tool enabled me to straighten them. Where the fins are mashed the hot exhaust air can’t escape.A few observations. The fins didn’t come out as straight as original, but straight enough to function properly. Also, it was a little more difficult than it appeared to align the tool teeth to the a/c fins. I had to gingerly adjust the position across the fins to get the tool teeth to align between the fins. If I inserted the tool before doing that, I would end up with more bent fins. Once the tool was inserted correctly, I had to pull straight down fairly hard to get it to straighten the fins.So that aspect was more delicate or intricate than I anticipated, but not difficult once I got up to speed with the tool nuances.This tool has four different tooth densities: 16, 18, 20, or 22 teeth per inch. From my experience it is essential that the tool tooth density matches the a/c fin density. If it doesn’t match, you can’t get the teeth inserted between the fins and I think you’re just going to mash in more fins. So having these tooth density options is good, it wasn’t too hard for me to count the fins per inch on my a/c to know which part of the tool to use. Still, I ended up putting Dymo labels on the outside of my a/c units identifying how many fins per inch. I don't want to have to count fins with a magnifying glass and a ruler again in the future if I can help it.This product is advertised as having a “resilient nylon comb” to avoid damaging the a/c aluminum fins, but I can’t help but think I might prefer a metal toothed comb. I think metal teeth, if they were thinner, might have been easier to insert and straighten more effectively.*** edited 7-10-24A year later I can't find my comb so I bought another, same product. I used the new one and some of the plastic comb teeth bent. Now for sure I wish I had a metal comb, but the Amazon descriptions of similar products are poor. Most don't indicate the material, even fewer indicate the teeth density. On many of the items the Amazon summary states "Recommended for hair, hair styling." I guess I'll make do.

Definitely works as intended. Many reviewers said the plastic was flimsy and gets eaten fast with the fins. Indeed, the plastic is flexible. But I have found that for my self, it is easier on the tool and to replace the fins to pull it up from the bottom to the top. And not doing it from top to bottom. From top to bottom, you are automatically using more force since you are pushing/pulling downwards. And when you push down, you also kind of push into the fins or away from you, that's just how it is. But putting yourself parallel to the unit and placing it at the bottom and pulling towards the top = less force and pulling ouwards instead of inwards... For me, that technique was best. I ordered this one because I needed the 20 FPI. It is best to try and calculate more or less what you need. One with a lower FPI will close more fins between them instead of opening them (say you use a 14 FPI on a 20 FPI). Would buy again, I am satisfied and has done the job to improve my central AC unit. Evidently it won't make it new but it helps it a lot.

I could not believe how easy to use this tool is. The results were incredible.The previous owner used a pressure washer to clean the coils, and flattened quite a few areas on the coil.The A/C repairman recommended getting a new coil, I never got a price, but I managed to straighten almost all of the fins for $50.Can’t beat that, this thing works and works well for anyone.

Although it looks and feels like its made decently , it does not do the job I expected, like the pro's say a thin blade and a lot of patience is needed to do the job right Now that i have bought it, and used it, it will be sold to the first taker.

Qualité du plastique des dents très moyen. Manque de rigidité et se déforme ce qui rendra sont utilisation difficile. Non recommandé pour les gens qui travaillent au quotidien avec ce type d'outils, pour dépannage seulement et encore?

This was the only one that I could find that the 22 fpi ( Fins Per Inch) rake (comb). My brand new window A/C was accidentally bumped into and a lot of the fins were flattened. Super quick delivery (ordered it Wednesday and it arrived Thursday).I found it worked best by inserting the comb into the fins by the rounded (backside) side of the comb and then pivoting the comb to the pointed (hook) side and SLOWLY but firmly drawing the comb down through the bent fins. It took me about 90 minutes to rake through all the fins. Granted it was not able to completely straighten all the fins (some were pushed tooo far in to come back out) but overall it worked GREAT. I am very happy with the results.The only downside of the comb is it is essentially a one time use. The teeth on the comb are made from a somewhat softer plastic and when finished using it, some of the teeth had broken off. But I guess if the teeth of the comb were any stiffer it may damaged the fins rather than straighten them.
