Here are a couple of other good manufactures of cable shield bond connectors:

ElectricMotion, makes two different sizes dependant on cable diameter. They use a shear off nut that shears @ 40 inch pounds (instead of using the t-handle torque wrench, for those of you that know what I'm talking about)

Hubbell, makes a great 12pr and down bullet bond, p/n BC285SB100

Thomas & Betts is a great connector too. p/n C4040. Some of you may of remembered this from when they were sold under the name of CTC. For those of you in high lightning areas, you may want to consider this connector. IMO.
