Nice Apollo O-816-1 Complete Primary Actuator Arm Kit Details
The Nice Apollo O-816-1 is a complete primary replacement actuator arm kit with a 12 ft cable for select Nice Apollo swing gate operator systems. It is used when the primary actuator arm on a compatible Apollo swing gate installation needs replacement and the site requires the complete primary actuator kit rather than an actuator-only replacement.
This kit is commonly associated with the Apollo 816-1 primary actuator family. Current 816-1 listings commonly describe the part as a primary actuator with 12 ft harness that includes the pivot arm and mounting hardware. Nice Apollo 816 manual references also identify related components such as the 1116 pivot arm, 10025215 gate bracket, and 1125 actuator hardware kit. Confirm current package contents before ordering or publishing the final included-items list.
What This Kit Does
The O-816-1 provides the primary linear actuator assembly used to open and close a compatible swing gate leaf. The actuator extends and retracts under control-board command, while the pivot arm, gate bracket, and mounting geometry determine how the gate travels. This kit should be matched to the existing operator system, cable length, and primary-side wiring before installation.
- Replaces the primary actuator arm on select Nice Apollo swing gate operators.
- Uses a 12 ft factory cable / harness for primary-side applications.
- Commonly sold as a complete primary actuator kit rather than actuator-only.
- Commonly listed with pivot arm and mounting hardware; verify current package contents.
- Works as part of a 12VDC electromechanical linear actuator system.
- Commonly used on select Apollo 1500, 1550, 1551, 1600, 1650, and 1651 swing gate systems.
- May be used with select 936, 1050, Mercury 310, and older Apollo control board families when wiring and system design match.
Compatible With
The Nice Apollo O-816-1 may be used with select Apollo swing gate systems that require the primary 816 actuator arm with a 12 ft cable. Always verify by the operator model label, actuator label, control board, cable length, bracket geometry, and parts diagram before ordering.

Important Compatibility Warning
Do not order this kit by the 816 number alone. Confirm whether the failed actuator is the primary or secondary side. The 816-1 primary actuator uses a 12 ft harness. The 816-2 secondary actuator used on many dual gate systems uses a 42 ft harness. The wrong cable length can cause routing problems, installation problems, or incorrect part selection.
Do not confuse O-816-1 with O-816 actuator-only listings. O-816-1 is typically positioned as the complete primary actuator kit with 12 ft cable and mounting hardware references, while some O-816 actuator listings may state that mounting hardware is not included. Confirm whether the current box includes the pivot arm, gate bracket, fasteners, and actuator hardware kit before publishing.
If the gate is dragging, sagging, binding, hitting hard stops, or mounted with poor actuator geometry, a new actuator can fail again quickly. Correct the gate condition before replacing the actuator arm.

Related Parts and Service Checks
- Confirm whether the job needs the 12 ft primary actuator or the 42 ft secondary actuator.
- Confirm the existing actuator label and cable length before ordering.
- Confirm whether the customer needs the complete kit or actuator-only replacement.
- Confirm whether pivot arm, gate bracket, and mounting hardware are included in current stock.
- Confirm the control board family and actuator wiring before replacement.
- Check the battery, charger, transformer, fuses, and wiring before assuming the actuator is bad.
- Check control board output under load if the actuator does not move.
- Inspect hinge condition, post movement, bracket placement, and gate stops.
- Confirm photo eyes, safety edges, and monitored entrapment protection devices are connected and working.
- Confirm push-to-open or pull-to-open geometry before reinstalling or adjusting the actuator.
Technician Note
The O-816-1 is usually the right direction when the primary actuator needs replacement and the installer also needs the kit components normally associated with the 816-1 primary actuator package. If the old pivot arm, gate bracket, or mounting hardware is bent, seized, missing, or worn, a complete kit may be a better choice than an actuator-only item.
The first field check is still cable length. If the actuator being replaced has a 42 ft cable on a dual gate system, this 12 ft primary actuator kit may not be the correct part. The 42 ft secondary actuator is normally handled under the 816-2 style reference.
Before Ordering Checklist
- Confirm the exact part number needed is O-816-1 or 816-1.
- Confirm the existing actuator uses a 12 ft cable.
- Confirm the failed actuator is the primary side, not the secondary side.
- Confirm the operator family is a compatible Apollo 1500, 1550, 1551, 1600, 1650, or 1651 system.
- Confirm the control board family and wiring are compatible.
- Confirm whether the kit includes the pivot arm, gate bracket, and actuator hardware kit.
- Confirm the gate leaf is no more than the rated length and weight for the operator system.
- Confirm the gate swings freely by hand without dragging, binding, or hitting hard stops.
- Confirm the battery, charger, power supply, wiring, and control board are not the real failure point.
- Confirm all required safety devices are installed and working before returning the gate to automatic operation.
Installation and Service Notes
The Nice Apollo O-816-1 should be installed by a qualified gate operator technician. Actuator replacement requires correct bracket geometry, cable routing, weather protection, control-board wiring, limit learning or setup, battery testing, and safety-device verification. Do not splice, extend, or reroute actuator wiring in a way that violates the current installation manual or creates moisture, voltage drop, or warranty issues.
For South Florida customers, Gate Openers Unlimited may be able to assist with availability and Hialeah Gardens local pickup when appropriate. Bring the old actuator label, control box photos, gate bracket photos, and cable length information when matching this replacement locally.
Professional Advisory
If the actuator failed because of a dragging gate, incorrect bracket geometry, water intrusion, lightning damage, a stuck relay, bad battery, weak charger, or unsafe wiring, replacing the actuator alone may not solve the problem. Do not bypass photo eyes, safety edges, emergency access, fire access, or operator safety circuits. Have unclear electrical, gate movement, or safety faults diagnosed by a qualified gate technician.
