Viking, All-O-Matic, and Apollo gate openers should be compared by gate movement, length, weight, traffic, and power supply. For buyers considering Viking, the Viking G5 pairs swing-gate operation with LCD diagnostics and adjustable speed; the Viking K2 and Viking L3 serve different slide-gate capacities. Compare those features with the appropriate All-O-Matic or Nice/Apollo model to select a complete system for your entrance.
These Viking gate opener reviews assess published manufacturer specifications, rather than hands-on test results or customer ratings. A higher weight rating does not necessarily suit a longer gate; match the length-and-weight limits and mounting arrangement before comparing controls or price.
The Apollo comparison below uses the Nice/Apollo TITAN 912L swing actuator. The slide-gate comparison includes the Nice Juno 310 as a related Nice-family alternative, not as a legacy Apollo model.

Gate operator selection: five requirements to compare
Use the same gate requirements when evaluating Viking, All-O-Matic, and Apollo:
-
Gate movement: Swing or slide, and single or dual leaves.
-
Dimensions: Weight and length of each swing leaf, or the complete sliding gate.
-
Traffic: Expected daily openings and the busiest periods.
-
Power: Available electrical supply, outage requirements, or a planned solar installation.
-
System components: Safety devices, remotes, keypad, intercom, or other access controls.
A linear actuator attaches to a swing leaf; a pad-mounted swing operator needs space for its base and operating arm. Have the installer confirm the mounting geometry as well as the published capacity.
Viking G5 vs. Nice/Apollo TITAN 912L for swing gates
The Viking G5 and Nice/Apollo TITAN 912L are linear actuators with different length-and-weight limits. Selecting the best swing gate openers for your entrance means checking both dimensions together:
|
Model |
Published gate-capacity examples |
What to investigate |
|---|---|---|
|
Viking G5, standard model |
2,000 lb at 10 ft, or 800 lb at 18 ft |
Whether its capacity at your leaf length and its V-Flex diagnostics suit the project. |
|
Nice/Apollo TITAN 912L |
1,000 lb at 8 ft, or 600 lb at 20 ft |
Whether the longer-leaf capacity and selected control-box configuration fit your gate. |
Sources: Viking G5 specifications and Nice/Apollo TITAN 912L installation reference manual. Published capacity points are not approval for every intermediate size; confirm the exact gate against the current manual.
Viking G5: Consider the standard Viking G5 when your gate fits the published capacity and you want V-Flex LCD diagnostics and adjustable speed. Viking lists the standard Viking G5 for residential and commercial use with a 100% duty cycle.
Nice/Apollo TITAN 912L: Consider the Nice/Apollo TITAN 912L for a longer swing leaf or a specified AC-charged or solar setup. Confirm the actuator and control-box configuration together.
A 20-foot, 600-pound swing leaf matches a published capacity point for the Nice/Apollo TITAN 912L. The standard Viking G5 lists 800 pounds at 18 feet; the separate 2,000-pound rating applies to a 10-foot leaf and does not establish suitability for a 20-foot gate.
Viking T21 vs. All-O-Matic SW-350DC PRO for heavy swing gates
For a heavy-duty swing gate opener with a pad-mounted layout, compare the Viking T21 with the All-O-Matic SW-350DC PRO. Check the installation space, gate dimensions, and exact motor version against these published specifications:
|
Model |
Published capacity |
Features to compare |
|---|---|---|
|
Viking T21 |
2,000 lb at 12 ft, or 1,200 lb at 20 ft |
V-Flex LCD diagnostics, removable power supply box, battery backup, and built-in heater. |
|
All-O-Matic SW-350DC PRO |
Maximum length: 22 ft. Maximum weight: 2,000 lb with ½ HP; 2,500 lb with 1 HP. |
Brushless DC motor, continuous duty, integrated battery backup, and mechanical foot-pedal release. |
Sources: Viking T21 specifications and All-O-Matic SW-350DC PRO specifications. All-O-Matic lists maximum length and weight separately; verify their permitted combination in the installation documentation.
The Viking T21 lists capacity at two specific gate lengths. The All-O-Matic SW-350DC PRO offers ½ HP and 1 HP versions with different maximum weight ratings, so a quote must identify the motor version as well as the model.
The Viking T21 displays AC line, surge-protection, and fuse status through the V-Flex LCD, giving the installer specific diagnostic information. The All-O-Matic SW-350DC PRO offers a mechanical foot-pedal release and two motor choices. Compare those features against service-access and manual-release requirements; the feature lists do not establish which operator lasts longer.

Viking slide operators vs. Nice Juno and All-O-Matic
Choosing the best slide gate operator starts with the gate’s weight, length, and intended use. The Viking K2 and Nice Juno 310 provide smaller-capacity examples; the Viking L3 and All-O-Matic SL-100DC PRO cover larger gates.
|
Operator |
Published capacity |
Useful comparison point |
|---|---|---|
|
Viking K2 |
700 lb / 30 ft |
Residential Class I model with V-Flex LCD diagnostics, battery backup, and Smart Positioning System. |
|
Nice Juno 310 |
800 lb / 40 ft |
A compact Nice-family alternative with Mercury 310 controls, AC or solar versions, driveway light, and integrated photo eye. |
|
Viking L3 |
1,600 lb / 60 ft |
Residential/commercial model with V-Flex diagnostics, removable power supply box, and Smart Positioning System. |
|
All-O-Matic SL-100DC PRO |
2,000 lb / 50 ft |
Brushless DC drive, continuous duty, integrated battery backup, and foot-pedal release. |
Sources: Viking K2, Nice Juno 310, Viking L3, and All-O-Matic SL-100DC PRO. These examples span different capacities; they are not interchangeable recommendations.
The Viking K2 and Nice Juno 310 differ in capacity and controls, including the Nice Juno 310’s integrated photo eye and driveway light. For larger gates, the Viking L3 lists a 60-foot maximum length, while the All-O-Matic SL-100DC PRO lists a higher maximum weight of 2,000 pounds. A longer rating and a higher weight rating solve different requirements; check both against your gate.

Solar power vs. battery backup: compare the exact configuration
A solar automatic gate opener uses sunlight to recharge the operating battery. An AC-powered system with battery backup uses the battery during a power outage. Check which arrangement the quoted model supports.
The Viking G5 Solar has a published capacity of 1,000 pounds at 16 feet, a 12V solar power supply, and LCD diagnostics. The standard Viking G5 has different capacity ratings; use the specifications for the exact version in your quote.
Source: Viking G5 Solar specifications.
The Nice/Apollo TITAN 912L has AC and solar configurations. The All-O-Matic SW-350DC PRO and All-O-Matic SL-100DC PRO also list solar capability, so solar support alone does not distinguish Viking from these alternatives. Ask your installer to check:
-
The exact operator and controller combination.
-
Battery capacity and the required charging equipment.
-
Available sunlight and the expected gate traffic.
-
The power demand of connected accessories.
TITAN configuration reference: manufacturer technical specifications.
A continuous-duty motor rating does not establish how many cycles a solar installation can sustain. The charging capacity must support the actual system load.
Viking, All-O-Matic, and Apollo pricing: compare complete quotes
Compare prices only after each quote covers the same scope. An operator-only price cannot be compared directly with a package that includes the controller, accessories, and installation.
Request comparable quotes that identify:
-
Exact model and version, including both operators for a dual gate.
-
Controller, enclosure, mounting hardware, and required cabling.
-
Battery and charging equipment, including any solar components.
-
Required compatible safety devices.
-
Receiver, remotes, keypad, intercom, or other access controls.
-
Installation, commissioning, and warranty conditions.
An itemized quote shows which components are included and which add to the installed cost. Use that total, together with model suitability and service support, to compare the proposals.
When is a Viking gate operator the right choice?
Choose a Viking model when the gate fits the published limits and the model’s controls or installation features meet a specific need:
-
For a swing gate: Consider the Viking G5 for a linear-actuator layout with LCD diagnostics and adjustable speed, or the Viking T21 for a pad-mounted layout with a removable power supply box.
-
For a residential slide gate: Consider the Viking K2 when its 700-pound/30-foot capacity fits and V-Flex diagnostics and the Smart Positioning System meet your requirements.
-
For a larger slide gate: Consider the Viking L3 when its 1,600-pound/60-foot capacity fits. Compare the All-O-Matic SL-100DC PRO if the gate requires a higher published weight capacity.
-
For solar: Evaluate the Viking G5 Solar using its own capacity rating and a charging configuration sized for gate traffic and accessory use.
Select All-O-Matic or Nice/Apollo when the specific alternative better fits the gate dimensions, mounting layout, power requirements, or local service support. Request the exact model and component list before placing an order.
