Q: What is the shortest length I could cut these friction lock controls back to? I would like one to operate a bellcrank behind the firewall. Regarding Part # 05-09436

The flexible housing is approx. 5-3/8" from the panel mounting point. The cable can be cut at that point, but you will need to cut longer than the 5-3/8" for the inner cable to attach it to to part / bellcrank.

Q: Could you please provide the weight of this control? Black knob / 36-Inch (05-09436)

The approximate weight of this control is 0.7 lbs.

Q: Can you please confirm the outside diameter of the cable housing and of the inner wire for the A-820 friction lock control?

The housing has a 1/4" O.D. and the inner wire is .078".

Q: What sized hole should I drill into the panel where the panel nuts lock the housing into place?

The A820 requires a 1/2" hole in the panel to secure the knob end of the cable to the panel.

Q: How do you clamp this A-820 friction lock cable? The 05-03287 cable clamp says specifically it will not work on the A-820. I am unable to find any other resources on your website. Thanks, Matt

The Cable Safe, P/N:05-16250, or Cable Safe II, P/N: 05-16252, can be used with an A-820 cable.

It is 36" from the panel mounting point to the tip.
