It is nice to cut just one hole . But it is a big one . I installed three of these on my Rv-4 engine control cables. They work well.

Great item. Works as described. Solid clamp on cable, the ability to angle the cable through 50 degrees is very helpful. Well worth the price.

Well built Eyeball firewall fitting, works well with good range of pass thru angle. Would be better if designed so the drill thru hole is a nominal size (1 instead of 1.06) so it could be drilled quickly with a step drill. Since the firewall should be made of Stainless, even enlarging it 0.060took more effort than drilling it to 1.00.
Very well made. Quality part.

The hole size you would need in the firewall for this part to fit would be 1.115".
These are finished in blue. We are updating our photo to reflect current finish.
The OD of the A-920 cable is 1/4 at the center of the control, you would need the .250.
This uses a 1-5/16 diameter nut.
