Works great to hold ACS Cables without a firewall jam nut. Just make sure your hole is of proper size. If you try and force it, this thing is made of aluminum and will easily strip the threads.

Q: What are these cable holder made out of? Regarding CABLE SAFE II

These are anodized blue aluminum.

Q: What is the difference between CABLE SAFE II and the other CABLE SAFE?

The Cable Safe II is a 2 piece housing (split) to allow for easier installation is some cases.

Q: What is the length of the threaded thru-the-firewall pipe-section? Product info request is for the Cable Safe and Cable Safe II.

The length of the threaded thru-the-firewall pipe-section would be 1.2". This is for both the Cable Safe and Cable Safe II.

Q: Can I use a CABLESAFE II with the A-800 control cable (spec'd as being 3/16 outer cable housing dia.)? If not, what would you recommend for firewall secure/penetration?

The A-800 that we stock have a 1/4" cable housing. So P/N# 05-16252 would work. If your cable does have a 3/16" cable housing then you would need to use 05-16252 along with the adapter which would be 05-16251. This will then work for your 3/16" outer cable housing.

Q: Cable safe II: What size hole is needed in the firewall for 1/4 inch cable?

You will need a .561" diameter hole in the firewall.

Q: What size hole is needed in the firewall for 3/8 inch cable safe?

5/8 inch

Q: Which direction should these be installed? Does it matter if they protrude forward or aft of the firewall?

These can be mounted either way.

Q: What is the maximum firewall thickness that Cable Safe will accomodate?

Approx 1".

Q: My control cables are 0.275 in diameter and am looking at the 05-16252. Will it accept the slightly larger cable or do I have to go with the 3/8 size? If so how then will it grip the cable?

05-16252 will not accommodate that cable. You would need to use the 3/8 size but it would not grip the cable since that would have around a .375 ID.
