Comparison of Full-Sized, Full-Matrix Portable Message Boards
This document presents a factual comparison of the INEX Spyder Platform and other full-size, full-matrix portable message boards. All specifications are sourced from manufacturer-published data as of 2026. No subjective evaluations or performance claims are made.
Theft Protection
Theft‑related features affect how easily a board can be removed from a job site or stripped for components. Tire count, battery placement, and fender construction all influence vulnerability.
| Feature | INEX Spyder Platform | Ver-Mac PCMS1500C | Wanco WTMMB | K&K MB14281 | Hill & Smith SMC 2000 FM ST | SolarTech Silent Messenger | AmSig CMS-T333 |
| Tires Left Onsite | 0 | 2 | 2 | 2 | 2 | 2 | 2 |
| Battery Protection | Elevated on mast, 13’ if raised | Lockable box on trailer deck | Lockable box on trailer deck | Sealed box on trailer deck | Lockable cabinet on trailer deck | On trailer deck | On trailer deck |
| Fenders | Welded-on | Bolt-on | Bolt-on | Unk | Unk | Unk | Unk |
Wind Stability & Structure
Wind stability is influenced by the deployed footprint and cabinet size. A larger footprint and lower center of gravity generally improve resistance to tipping.
| Feature | INEX | Ver-Mac | Wanco | K&K | Hill & Smith | SolarTech | AmSig |
| Deployed Footprint | 11’x12’ | 11’x7’ | 12’x8’ | 11’x7’ | 11’x8’ | 12’x8’ | 10’x7’ |
| Cabinet Size (W×H) | 68”x120” | 83”x145” | 75”x138” | 81”x142” | 8”x133” | 76”x126” | 80”x138” |
| Wind Stability Factor | 1.48 | 0.33 | 0.50 | 0.31 | 0.44 | 0.77 | 0.58 |
Wind stability factor is calculated from footprint and cabinet size.
Power System
Power system components determine runtime, charging efficiency, and long‑term maintenance requirements. Solar wattage, controller type, and battery chemistry all play a role in operational autonomy.
| Feature | INEX | Ver-Mac | Wanco | K&K | Hill & Smith | SolarTech | AmSig |
| Std Solar Wattage | 480W | 330W | 130W | 140W | 140W | 160W | 80W |
| Std Controller | MPPT | PWM | PWM | PWM | PWM | PWM | PWM |
| Std Battery Type | LiFePO4 | SLA/Gel | SLA/ Flooded | SLA/AGM | SLA/ Flooded | SLA/Gel | SLA/ Flooded |
| Lifespan | 10–15 yrs | 3–5 yrs | 2–4 yrs | 3–5 yrs | 2–4 yrs | 3–5 yrs | 2–4 yrs |
| Useful Watt-Hours | 3014 | 2640 | 2580 | 3960 | 1320 | 3120 | 2640 |
MPPT controllers capture more usable energy from solar panels, especially in cloudy/low-light or winter conditions—while PWM is simpler but much less efficient.
Total watt‑hours are a good indicator of how long a message board can operate without any solar input.
Platform
Platform construction affects stability, durability, and ease of deployment. Weight, ballast type, and mast lift design all contribute to operator experience.
| Feature | INEX | Ver-Mac | Wanco | K&K | Hill & Smith | SolarTech | AmSig |
| Weight | 3120 | 1860 | 2100 | 1655 | 1875 | 2900 | 3000 |
| Ballast | Built-in | Sandbags | Sandbags | Sandbags | Sandbags | Sandbags | Sandbags |
| Mast Lift | Balanced | Unbalanced | Unbalanced | Unbalanced | Unbalanced | Unbalanced | Unbalanced |
Balanced means no pin is needed to keep sign from slowly lowering when the pump turned off.
Jack Stands
Jack stand height, capacity, and footplate design influence stability during deployment and in high‑wind environments.
| Feature | INEX | Ver-Mac | Wanco | K&K | Hill & Smith | SolarTech | AmSig |
| Ext Height | 29″ | 10″ | 15″ | 15″ | 15″ | 13″ | 10″ |
| Capacity (lbs.) | 5000 | 2000 | 2000 | 2000 | 2000 | 2000 | 3000 |
| Footplate | Swiveled, cleated | Rigid flat | Rigid flat | Rigid flat | Rigid flat | Rigid flat | Rigid flat |
Mast & Cabinet
Frame gauge, cabinet material, and door construction affect durability, weather resistance, and long‑term maintenance.
| Feature | INEX | Ver-Mac | Wanco | K&K | Hill & Smith | SolarTech | AmSig |
| Frame | (7-gauge) | 11-gauge | 11-gauge | 11-gauge | 11-gauge | 11-gauge | 11-gauge |
| Cabinet | Steel | Aluminum | Aluminum | Aluminum | Steel | Steel | Aluminum |
| Door polycarbonate | 0.220″ | 0.125″ | 0.187″ | 0.150″ | 0.187″ | 0.187″ | 0.125–0.250″ |
