Part# 05-08660
MFR Model# A-800-BL-0600


The A-800 friction lock control provides positive locking at any power setting by turning the chrome collet locking nut. Unique ball-socket construction permits 10-32 threaded end to swivel 8 degree in any direction. Casing has Teflon liner for low friction and heat resistance in high-temperature areas such as engine compartments. Travel: 3-3/8". The 1-1/4" dia. solid knob is available in black or blue (blue knob has smooth profile, not FAA style). 1/2" panel thread. Lengths are measured from under panel nut to end of threaded shaft with knob pushed in.

Made in USA


I did not use this. I messed up by ordering the wrong length. Measured 2 from the instrument panel to the firewall and then 4 feet from the firewall to where the end of the cable would be. Then I preceded to order a 4 cable instead of a 6 cable.

Great cable and great price. As the other review says, the knob is a little rough. I removed the knob, put it in the lathe and was able to quickly smooth out the mold lines with some 400 grit sandpaper. Then with a light touch of flame from the torch the knob came out smooth and glossy, looks great and feels good in your hand.

Nice good quality throttle cable that is more than adequate for my needs especially at 1/4 the cost of the quote I got from Mc-- for essentially the same unit. My airplane had the same ACS throttle only with a vernier control which I discovered I very much didnt like the first time I had to do a go around. With a vernier throttle you find yourself hunting for the release button to add power when time is critical. Thats a non player in my book after 40 years of aviating. The knob, although standard, is a little chinsier looking that the other brand but I was going to replace it with a nice aftermarket carbon fiber or billet alum shift knob from eBay anyway.

Q: Are the knobs on these throttle controls removable? If so, what is the thread where it attaches?

A800 control knobs are threaded on with Loctite 262. It has 1/4-28 threads.

Q: What is the outside cable diameter for firewall penetration?

The largest diameter is approximately 3/8".

Q: What is the outside cable diameter for firewall penetration, not the largest diameter but the cable's diameter? Regarding A-800 friction lock control.

1/4" O.D. on the cable but the swaged on part is 3/8". Customer would need to drill a 3/8" hole and use a AN931 grommet.

Q: Diameter hole for the instrument panel?

The diameter for the hole would be 1/2".

Q: What is the length of the threaded portion of the cable?

The threaded section is .70".

Q: What is the length with the from the hold down clamp notch to the end of the dust cap with the cable retracted to the dust cable?


Q: Can the A800 threaded 10-32 rod be cut and shortened like the solid wire of the A820?

No, it is not recommended that these controls be cut.

Q: What kind of thread is at the end of the cable?

This will have a 10-32 threads at the end of the cable.

Q: Does the Vans A-800 have a bulkhead mount on the end of cable for attaching to a bracket mounted on the carb?

Yes the Vans version of the A-800 has a bulkhead mount. See Part# 05-01436 for Vans version.

Q: I am confused. What is the difference between a Vans A-800 (eg. 05-08660) and a regular A800. I ordered a 05-08660 thinking I was getting a 5 cable with bulkhead connection on the end. Instead it looks like a standard A800 connection

The Vans cable (Part# 05-01436) has the threaded bulkhead a the engine end and you can order it in custom stroke lengths.
