NICE / APOLLO A2027, EXTENSION TUBE FOR 816 ACTUATORS
The Nice Apollo A2027 extension tube is a replacement tube for compatible Apollo 416 and 816 style linear swing gate actuators. The extension tube is part of the moving actuator assembly that extends and retracts as the gate opens and closes. It must remain straight, clean, and properly aligned for smooth travel. This part is commonly replaced when the original tube is bent, scored, corroded, damaged from impact, or worn from poor alignment or seal failure. A damaged extension tube can cause grinding, binding, limit problems, and extra strain on the motor and screw-drive components. Before ordering A2027, verify the actuator model and check related parts such as the cover tube, seal, main screw, gear nut, and front housing.

Technician Note
A bent or scored extension tube usually points to a larger problem, such as impact damage, poor gate geometry, a sagging gate, or a damaged seal. Correct those issues before putting the operator back in service.
Before Ordering
- Confirm whether the actuator is a 416, 416X, 816, or 816X style arm.
- Check the original parts diagram for A2027 extension tube use.
- Inspect the cover tube, seal, screw drive, gear nut, and front housing for related damage.
- Verify gate brackets and hinges are aligned so the actuator does not bind through travel.
- After repair, test the gate manually and under power with proper safety devices operating.
Professional Advisory
Gate operator parts should be installed with power disconnected and the gate secured against movement. Actuator repairs can affect travel limits, force, and safe gate movement. For electrical diagnosis, internal actuator service, or any unsafe gate condition, use a qualified gate technician. Do not bypass photo eyes, safety edges, alarms, or other required safety devices.
Important Ordering Warning
A2027 is the extension tube only. It is not the complete actuator, cover tube kit, main screw, or seal housing.
Product Questions & Answers
What is the A2027 extension tube?
It is the moving extension tube used in compatible Apollo 416 and 816 style linear actuators.
Does A2027 fit Apollo 416 actuators?
Yes, it is commonly listed for 416 and 416X actuators when the actuator configuration matches.
Can a bent extension tube cause the gate to bind?
Yes. A bent or scored tube can create drag, noise, uneven travel, and extra load on the actuator motor.
Is A2027 included in A2024K?
A2024K is a cover tube and seal housing kit. Do not assume it includes the A2027 extension tube unless the specific package contents confirm it.
What related parts should be checked?
Check the seal, cover tube, main screw, gear nut, bushings, bearings, and actuator mounting geometry.
