103B — Black flush-mounted van rear ladder
Adjustable 46–50-inch rear-door ladder, black powder-coated aluminum
View 103B productSurco 103B, 103H & 103HF Van Rear-Door Ladders: Mounting Guide
Surco makes several four-rung aluminum ladders for reaching the upper rear area of a van. The similar-looking models are not all mounted in the same way: 103B uses a direct flush mount, while 103H and 103HF have an over-door hook arrangement. Choose by the door and body construction first, then check the mounting locations and ladder height.
Find the correct rear-door ladder
| Surco number | Mounting style | Manufacturer length | Finish and application |
|---|---|---|---|
| 103B | Flush-mounted; adjustable height | 46–50 in | Black powder-coated; universal-style van application |
| 103H | Over-door hook; fasteners required | 52 in | Bright-dipped aluminum; Chevrolet, GMC and Dodge van applications listed by Surco |
| 103HF | Ford over-door hook; fasteners required | 50⅜ in | Bright-dipped aluminum; Ford van application |
All three models use 1-inch aluminum tubing and grooved non-slip steps. Surco lists an 11-inch centre-to-centre rail spacing, 12¾-inch outside width and 250 lb capacity. These dimensions describe the ladder family, not a guarantee that the mounting points line up with every rear door.
How the mounting arrangements differ
103B flush mount
The ladder mounts directly against supported rear-door/body locations; its 46–50-inch height can be adjusted to suit the application.
103H hook-over
Curved top hooks engage the suitable door edge, with additional fastened attachment specified by Surco.
103HF Ford hook-over
Ford-specific hook-over profile and 50⅜-inch overall length; match the door shape and mounting area before drilling.
Simplified identification guide, not a drilling template or a scaled manufacturer installation drawing.
Hook-over does not mean tool-free installation. Surco specifies drilling for its 103H and 103HF as well as the flush-mounted 103B. Follow the model's factory instructions and confirm reinforcement in the actual door or vehicle body. A thin or unsupported panel should not be used as the sole ladder support.

View 103HF productBefore choosing or installing a van ladder
- Identify the exact vehicle and rear-door style. Compare the original ladder or Surco's current fit information rather than assuming all model years use the same door.
- Measure clearance around hinges, locks, windows, rear lights and any fitted accessories.
- Check the required ladder height, the distance between mounting rails, and the supporting structure.
- Follow the manufacturer's mounting and sealing instructions, and confirm the door can travel through its full opening range afterward.
