Universal Turn-to-Lock Controls
Perfect for homebuilt or custom projects
These versatile controls are ideal for many applications. They feature a turn-to-lock mechanism that requires a quarter turn of the knob to lock or unlock the control.
Multiple options:
- Knob styles
- Inner wire size
- Length
- Dual or single wire/conduit
Many applications:
- MCTL1014D series controls are ideal for choke controls for Rotax engines with dual carburetors
- Quality stainless steel construction
- High temperature Teflon lined conduit for smooth, consistent control
(Cheapy controls with poly liners will not tolerate engine temperatures) - Wire end – may be trimmed to length
Specifications:
- Travel (stroke): 3.5″ minimum
- Conduit (dual wire controls): 0.188 inch OD Teflon lined wound conduit
- Conduit (single wire controls): 0.25 inch OD Teflon lined wound conduit with a Teflon jacket
- Max Work Loads: Pull: ~25 lbs; Push: ~10 lbs*
- Operating Temp: -65 to 450 deg F (knob/housing assembly: -65 to 250 deg F)
- Panel Fitting: 1/2-20 UNF thread
- See McFarlane Turn-to-Lock Controls for further specifications.
*Push loads apply to controls with solid wire only and depend on wire diameter, length of trimmed wire (unsupported by conduit), geometry of wire rigging, and the actuator configuration.

Frequently Asked Questions
How do I clean and sanitize a McFarlane Push-Pull Control?
We make the following cleaning and sanitizing recommendations to be completed between flights: Recommended Cleaning Process 1. Put on clean disposable gloves prior to cleaning and disinfection. 2. Pull controls back to the fully retracted position to expose the full length of the control shafts. 3. Apply isopropyl alcohol to a clean microfiber towel. Do not spray any solution directly on the controls or any other surfaces or components in the aircraft. !!! WARNING: DO NOT USE BLEACH WIPES ON ANY MCFARLANE CONTROL !!! 4. Gently and thoroughly wipe down every control knob surface and control shaft. 5. Let cleaning solution dry on these surfaces (contact time). 6. Use a clean and dry microfiber cloth to wipe away any solution residue left on knob and control shaft surface. 7. Remove all gloves, towels, and cleaning supplies from the work area in the aircraft. Please contact McFarlane Sales directly at 866-920-2741 or 785-594-2741 or sales@mcfarlaneaviation.com if you have any additional questions regarding the disinfection of our controls.
What is the minimum bend radius for my engine control?
McFarlane's Storage and Packaging Specification requires a specific packaging minimum radius based on the length of the control, type of wire used, and the configuration of the control end(s). Please contact us to determine the exact requirements for your specific control.
How do I trim my engine control to length?
Please reference the Installation Instructions included with your new control.
I purchased a laser engraved knob and the thickness of the marking is very shallow. What kind of wear resistance can I expect?
The laser marking does not harm the hard durable anodize coating on the aluminum knob. The CO2 laser process only bleaches the color from the anodizing leaving a silver white color that contrasts with the surrounding dyed anodize. The durability of the laser marked area is not affected by the laser. Our tests have shown that the laser process actually improves the corrosion resistance of the anodize layer. The CO2 laser engraves aluminum knobs by vaporizing the surface leaving a deep durable groove. This groove is then filled with a special paint for contrast. The result is a durable long lasting mark.
