Questions & Answers

I was wondering if you had anything in your listing for especially the blue insulated or any other staple to be used as an anchor point for a 21s cable tie to support a bundle of nm cables. I know that a great many electricians use them this way successfu

Answer This Question

Very good question. Why that wouldn’t be a very important spec to include is beyond comprehension.

    What's the inner dimension, between the two "posts"? I'm assuming 9/16" is the outer dimension.

    Are they approved for use in pressure treated wood?
    ByMar 7, 2023

    Answer This Question

    Hey Bob, you'd need to get confirmation from local code just to be sure but staples used in pressure treated wood need to be stainless steel. These do not meet those requirements, though we do have stainless steel staples in our Briscon staple line(SN40BSS25 and SN40IBSS20). Hope this helps!

      You can't, they're manually installed the good old fashion way with a hammer, and sore thumbs

      Hold tight and don't damage the wire. Essential item for safety keeping the wires from moving around. The pack has 200 staples which is great. Always need more than you think.

      Perfect staples for the old wood in my house, they are tough enough to be hammered into brittle wood without bending. The plastic strap is nice for protection as well. I use these with 12 and 14 gauge but they will work up to 10/3. These will rust if exposed to water.

      Does what you'd expect. Packaging is good and they are very sharp, which makes it easy to start them, at least in soft woods. However they did seem prone to bending. I was using them in an awkward corner, so my swing definitely contributed, but they'd often be used in awkward spots. On a side note, I was looking for screw-down zip ties and couldn't find any, then I thought I could use these to anchor down regular zip ties and it worked great.

      I used these to attach 1/4 inch hardware cloth to a square wooden frame to sift dirt from gravel that had been left at a drop off point. The insulation strip was removed. It worked very well and the price was a fraction of the u nail price.
