## Overview

The Malco FST2 Fin Straightening Tool is a USA-made, durable fin comb designed to straighten closely spaced aluminum fins (16-22 fins per inch) on condenser and evaporator units. Featuring adjustable one-piece nylon combs that prevent damage, ergonomic offset handles for comfort, and versatile push-pull functionality, it delivers professional-grade fin repair in tight or multiple-pass scenarios.

## Description

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.

Review: Works - Worked very good. It did start breaking down towards the end. Has the correct sizes.
Review: Poor quality check - One of the combs (which is the one I needed) wasn’t straight and it seems like it had manufacturing plastic left over which without the bent would probably be a problem anyways.

## Questions & Answers

**Q: Are the combs metal on this model? FST2**
A: The combs are plastic, and pretty tough. I have put one of the combs through about 30 hours of tough work, about 100 square feet of coil area, and the comb is still in very good shape.  Repairing closed-off fins can be slow and difficult, but brings new life into those expensive condensing units.

**Q: The description for this malco fst2 fin straightening tool says it's for 16, 18, 20 or 22 fins per inch. does that work for a window air conditioner?**
A: I'm afraid I do not have a real answer.  Mine did not work for my car's AC condensor, the fins were too far apart for the tool even at the 16 setting.
Measure the # of fins per inch is my best guess.

**Q: what setting is good for home AC units?**
A: It has four different sizes. I use it on my window units. It can be difficult to use but it does work. Not sure if it will fit a home unit but it should.

### ⭐⭐⭐⭐ This did the job.
*by G***O on July 19, 2023*

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 7-10-24 A 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." It's not that kind of a comb.
