When a company has been around as long as Klein Tools, you have to figure it has a finger on the customerโs pulse. Kleinโs 160 years of tool-making experience convey a certain expectation of form and function. The same goes for the Klein 9125K 25-Foot Double Hook Magnetic Tape Measure. Journeymen electricians like meโand every other tradesmanโwill always need an accurate and wieldy tape measure for our work. Thatโs the promise of this particularย Klein magnetic tape measure, so letโs see how it works.

First Impressions
The tape measure body is an orange composite material with several large areas of rubber overmold for protection and gripping. ย The slightly curved top feels good in the hand.ย The brake that runs along a good portion of the bottom really stands out. It conveniently keeps the blade from retracting without having to use the lock while allowing quick retraction when youโre finished with a measurement.
Some tape measures (see our best magnetic tape measure article), have an open area where you essentially use your index finger as a break. The Klein brake can be operated with the index, middle, or even ring finger. It doesnโt sound like a big distinction, but itโs helpful in practice.
Speaking of stand-out features, Klein claims a 9.5-foot standout of the nylon-coated steel tape, and it seems to hold up to a bit more. It wonโt have the standout of wider tapes like the Stanley Fatmax tape measure, but thatโs the trade-off for a relatively smaller profile. You donโt always have someone else to hold the other end of the tape, so a long standout is essential. Other notable features include thingsย youโd hope to have in a professional tape measure. This includes the magnetic double-sided tang, double-sided gradation markings, a nylon coated blade, tape lock, a belt clip, and even a conduit bending table for offsets and saddles. Letโs see how it measures up.

Measuring Up the Kleinย Magnetic Tape Measure
I recently began installing electrical service on a building that had been abandoned and neglected for quite some time. Itโs part of the revitalization of a blighted commercial district thatโs attracted theย attention of the local economic development council as well as some start-up businesses. Iโm thankful to be a small part of this project but, as anyone who has retrofitted older buildings can tell you, it can be full of surprises. This was the perfect location to see howย the 25 ft. Klein magnetic tape measure performed.
I used the Kleinย magneticย tapeย measure to lay outย conduit, wire, and distances for this installation. It performed really well and, as I suspected, the brake was very handy. The double-sided tape is very easy to read. If youโve ever tried to contort yourself to get a single-sided tang to hook onto an edge, youโll appreciate the double-sided tang on the Klein. This has become a standard feature on professional tapesโand for good reason.

The 25 ft. Klein magnetic tape (model 86225) weighs 17.6 ounces. Itย feelsย just right, especially since Iโve had tapes that feel like a brick. Itโs not burdensome when clipped on your pocket or belt. But it isย slightly heftier than say, Milwaukeeโs comparable tape at 12.8 ounces. Then again, the Milwaukee doesnโt have the brake that I like so much on the Klein but instead usesย an open area.

Klein Magnet Issues
The only area of theย Klein Tools magnetic tape measure that needs improvement is the magnet. I had an older Klein whose magnet was attached to the end of the tang. That thing held fast to any metal. The one on this new tape isnโt as strong. I found it pulled away about 25% of the time I needed it to stick. A stronger rareย earth magnet would make this tape a home run for Klein.

The Bottom Line
The 25-foot Klein magnetic tape measure with a double hook has a composite body with lots of rubber overmold for grip and protection. It boasts a nylon-coated,ย double-sided steel tape with a magnetic double tang. The shining feature of this overall solid tape is the long brake, which allows the user a wide area to temporarily stop retraction without using the tape lock. Itโs a better design than tapes that have an open area for your finger to act as the brake.
I found the gradations on both sides of the Klein Tools 25-foot double hook magnetic tape measure easy to read, and the coating held up really well in my work environment. You can find lighter tapes, but the Klein isnโt too heavy at 17.6 ounces. It wonโt feel like a burden when clipped on your pocket or belt with its wide, easy-to-use belt clip.
Pricing and Final Thoughts
I donโt think tradesmen will ever refuse having a longer standout. Many times you just donโt have someone to hold the other end of the tape. Klein claims a 9.5-foot standout, and I found it to be over 10 feet. Still,ย Iโd take more! The one true weak spot of this tape: the magnet strength needs to be increased. At around $20, however, I can easily recommend it.
