Ulsa Tools Heat Shrink Handle Covers: A Cheap Upgrade for Worn Tool Handles

Introduction

Ulsa Tools, based in Canada, recently released a set of heat shrink handle covers aimed at people who want a better grip on their hand tools without spending much. The pack sells for about $7.87 and includes four sizes in a single color. The colors offered are green, blue, red, and black.

If you have ever bought small packs of heat shrink tubing, you already know the colors tend to be boring, and multi-color sets usually force you to buy far more than you need. This set simplifies that: one color, four sizes, one low price. Here is how it performed on a variety of real workshop tools.

What You Get

Each pack contains four different sizes of tubing in your chosen color. The shrink ratio is 2:1, which is the most common ratio on the market. That means the tubing shrinks to half its original diameter when heated. Higher ratios like 4:1 or 6:1 exist but are harder to find, so planning around 2:1 is the practical reality for most buyers.

At a 2:1 ratio, the sizing rule is simple: pick the smallest size you can comfortably slide onto the handle. The tighter the fit after shrinking, the better the result.

Installation: Simple, With a Few Tricks

Installation only requires a heat gun. A careful hand with some kind of torch gun can probably work too, but a heat gun is the safer route. Cut the tubing to length, slide it on, and apply heat evenly until it contracts snugly.

A few practical lessons came out of testing on four different tools. First, on a handle with a mushroomed or flared end, the tubing can be hard to get past, so check the fit before committing. Second, work from the smallest size that fits, because stepping up a size leaves looseness once it shrinks.

Marking and Protecting Your Tools

The covers are not just for grip. On a beat-up old chisel that had become hard to tell which end was which, a short section of green tubing made the tool easy to identify at a glance while also adding purchase on a slippery shaft.

Handles with details like hanging holes need a bit of planning. Marking where the hole sits before cutting ensures the hole stays exposed after shrinking. One useful discovery: the tubing carries marks that appear to indicate where the shrink ends, which makes cutting to length considerably easier. Cutting just under the mark and shrinking produced a snug fit with no gap.

The Comfort Grip Experiment

The most interesting use case was covering a soft rubber comfort grip handle. Rubber grips on ratchets and similar tools tend to get chewed up over time and hold onto dirt. The idea was to see whether a shrink cover could protect the grip while retaining its comfortable feel.

The answer, after shrinking a blue cover into place, was a clear yes. The covered grip felt noticeably better in the hand than the worn rubber alone, with the tubing conforming tightly and no gap. It adds a durable outer layer while keeping the cushioned feel underneath.

Things to Consider Before Buying

The 2:1 ratio works well but limits how much taper a single cover can handle. On a scraper with a shape that tapers down before rising again, one continuous cover was not going to fit everywhere, so the solution was to cover a section and stop before the taper. If your tool has dramatic shape changes, plan on covering specific sections rather than the whole handle.

Cutting accuracy matters too. A careless cut shows after shrinking, though the fit itself stays secure. Take your time with the scissors.

Buying Advice

For roughly $7.87 a pack, these are an inexpensive, low-risk way to refresh old handles, color-code your tools, protect soft rubber grips, and add grip to bare steel shafts. Testing across a square-shaft brake tool, a carbide scraper, a chisel, and a rubber grip produced four successful fits with no failures.

Pick your color based on whether you want the tool to disappear in the drawer or stand out on the wall. Choose the smallest size that slides on, cut just under the guide mark, and shrink evenly.

Conclusion

Ulsa Tools Heat Shrink Handle Covers deliver exactly what a workshop accessory should: a cheap, effective fix that requires no special skill beyond a heat gun and a little planning. With four sizes per pack, a 2:1 ratio, and a choice of four colors, they are an easy recommendation for anyone with worn, slippery, or hard-to-identify hand tools.
