PRINIC Trailer Document Holder 8-Pack — Opaque Grey ABS with Smoke Polycarbonate Lid, Wire-Attached Covers

PRINIC’s 8-pack trailer document holder is a weather-resistant, wire-attached registration card case made from ABS with a smoke polycarbonate lid to keep trailer paperwork visible and protected.

Keep registration, insurance, and inspection papers secure and readable on trailers, trucks, and semi-trailers with this durable document holder kit. Each unit combines an impact-resistant ABS body with a sealed smoke polycarbonate cover and an attached wire to prevent loss. The compact design mounts easily, creating a dedicated, visible storage spot for essential documents exposed to road, sun and moisture.

How big is each document holder and what will fit inside?

Each holder measures 6" x 5" x 2" externally, with an internal cavity 3-3/4" in diameter and 1" deep, sized for folded registration cards, small certificates, and similar papers. It’s optimized for common trailer documents rather than large folders.

• Outside dimensions: 6" x 5" x 2"
• Internal opening: 3-3/4" diameter
• Internal depth: 1"
• Best for folded cards, registration slips, and thin certificates

What materials and protections does it provide?

The outer shell is molded from ABS plastic while the lid uses smoke-colored polycarbonate, combining strength and clarity. These materials resist corrosion, impact and UV degradation so documents remain intact and readable in harsh transportation environments.

• ABS body for impact and weather resistance
• Polycarbonate smoke lid for visibility and toughness
• UV and corrosion resistant for long-term outdoor use
• Sealed cover to reduce water intrusion

How does the cover and attachment work to prevent loss?

The cover is spring-securable to the base and includes a wire attachment so the lid stays connected when opened. The smoke cover is waterproof and remains sufficiently transparent to read inserted documents without removing them.

• Wire-attached cover prevents accidental loss
• Spring-fit lid locks to the base securely
• Waterproof seal protects against rain and spray
• Smoke tint maintains document legibility

How easy is it to install and maintain on a trailer?

Installation is straightforward and requires common fasteners; the compact shape mounts on flat trailer surfaces or near the hitch. Routine maintenance is limited to occasional lid and seal inspections and wiping away road grime to keep contents visible.

• Mounts with screws or bolts to flat surfaces
• Simple one-person installation
• Minimal upkeep—clean and check seals periodically
• Works on trailers, semi-trailers, trucks, and utility vehicles

Who is this for: Fleet managers, owner-operators, rental yards and anyone who needs a compact, reliable place to store trailer registration and inspection documents on the exterior of a vehicle. The 8-pack format suits small fleets, garages, or repair shops that want uniform, weatherproof document storage across multiple trailers or trucks.
