When I worked for the cable companies the T25 was the standard until they switched over to RG6. Not unusual to find a problem because of a staple through a cable. Can't say that I ever did that though, if I did I knew it and replaced the cable.

Then with telecom the T18 was made for JK station and ground wire. Later on I went into key systems that used 4 pr CAT3 and used the old T25 again. The only stapler I hated was the T75 with 25pr. That one would always shoot a leg through the cable and re-running 25pr wasn't cheap.
