Overview
A magnetic hook that grips steel and reads true from zero lets this Stanley keychain tape take inside and outside measurements in a small space. The coated blade resists wear, a slide lock holds it out, and a key ring carries it everywhere.
Always having a tape on you is the reason to buy it, from shopping for furniture to checking a part. The magnetic hook frees a hand on metal. The blade is short, and one spec line lists a different length than the bullets.
Who it's for
Homeowners, shoppers and techs who measure small items often will use it daily. Builders and anyone measuring walls need a full-size tape.
Pros and cons
- Fits on a key ring
- Magnetic hook grips steel
- Stud center marks printed
- Polymer coated blade
- Short blade for room work
- Blade length conflicts in specs
- Narrow blade limits standout
Performance notes
Accuracy depends on the hook sliding the right amount for inside and outside readings, which the Tru-Zero design handles. The narrow blade bends easily, so it reads most reliably when supported on a surface. The coating slows wear on the printed marks.
