Single-strut: 24″, 40″, 60″ • Double-strut: 40″, 60″ (extra rigidity for frequent use and deep-trailer reach).

Short-reach arm ideal for compact bays and shallow trailers; lightweight and easy to adjust.

Extended single-strut arms provide longer reach while staying easy to maneuver.

Dual-strut design adds rigidity and stability, ideal for frequent repositioning or vibration-prone docks.

The longest and most stable arm for deep trailers and heavy-duty, high-frequency operations.
| Arm Type | Length Options | Best For | Key Advantages | Notes |
|---|---|---|---|---|
| Single Strut | 24″ / 40″ / 60″ | Shallow to medium-depth trailers, standard use | Lightweight, flexible, cost-effective | 60″ Single Strut provides the longest reach |
| Double Strut | 40″ / 60″ | Deep trailers, high-frequency docks, vibration | High rigidity, stable positioning, and durable | Recommended with higher lumen output / clear glass |
Arm Naming (Model Mapping):
A1 = Single Strut 24″/40″ •
A2 = Single Strut 40″/60″ •
B1 = Double Strut 40″/60″ •
C1 = Double Strut 40″/60″
Selection Tips:
Choose 24″/40″ single-strut for shallow bays; 60″ single-strut for deeper trailers; 40″/60″ double-strut for high-frequency, heavy-duty, or vibration-prone environments.
