Klein Cable Stapler

Klein designed it for simple one-handed operation. The handle is designed to be pushed rather than squeezed, making for easy and consistent performance. The ergonomic “reverse” action reminds us of the popular Arrow Powershot 5700 stapler.

Klein acknowledges that many cable staplers exist on the market, but maintain that they have an advantage over others. This comes down to the adjustability of theirs. It can handle multiple insulated staple sizes, working with 1/4″, 5/16″, and 11/32″ insulated staples. It works on various jobs that call for anything from speaker wire to CAT3-CAT6A, Coax, or even Romex 14/2-12/3G.

Klein fashioned this lightweight stapler from cast aluminum which also gives it better durability over steel. It has cushioned grips for easier stapling—helpful if you do a lot of staples in sequence. You can adjust a force setting lever to dial in the power, and a cable guide keeps your work neat and tidy.

You can pick up the Klein Loose Cable Stapler for $39.97. It comes with Klein’s Limited Lifetime Warranty that they include with all their hand tools.

Worst stape gun I’ve had in over 30 years. Only works about 50 percent of the time. Very dissapointed in Klein. 40.00 paper weight.


Stapler works great, they do pull out a little easily though. Biggest complaint is they STILL don’t have the staples for 12/2 and 14/2! It’s the most common wire size. Why did you not start with that size? It’s been a few years what is the deal Klein?

Would love your thoughts, please comment.x
