PRINIC Trailer Document Holder 8-Pack — Opaque Smoke ABS holders with wire-attached cover and weatherproof protection

PRINIC's 8 Pack Trailer Document Holder is a rugged, wire-attached registration card case that protects paperwork on trailers and trucks.

Keep permits, registration cards and important transport documents safe, dry and visible with this ABS plastic document holder kit. Each holder features a polycarbonate smoke cover that seals against weather and a spring-fixed lid that keeps a single card readable while preventing loss. The compact external size fits most trailer mount points while the internal cup holds a single circular card or folded papers securely.

How durable is this document holder under road conditions?

The body is molded from impact-resistant ABS and the lid from UV-stable polycarbonate to withstand vibration, moisture and sun exposure. Corrosion-resistant materials mean the case lasts longer in salty, wet, or dusty environments.

• ABS body resists impact and cracking
• Polycarbonate cover endures UV without yellowing
• Sealed smoke cover keeps water and dust out
• Wire-attached lid prevents accidental loss on the road

What size documents will actually fit inside the holder?

The internal cavity is a circular cup 3-3/4 inches in diameter and 1 inch deep, sized to accept most circular registration discs or folded rectangular papers. External dimensions are 6" x 5" x 2", so the unit mounts neatly without protruding excessively.

• Internal: 3-3/4" diameter × 1" depth for discs and folded cards
• External: 6" × 5" × 2" for compact mounting
• Opaque smoke cover keeps documents readable while protected
• Wire attachment keeps cover secured to the base

How easy is installation and everyday use?

Installation is straightforward—mount the base to any flat surface on trailers or truck frames using standard fasteners. The spring-fixed cover snaps into place for quick access and the attached wire ensures the cover remains connected when opened.

• Simple screw- or bolt-mount on flat trailer surfaces
• Spring-lock cover for one-handed access
• Wire tether prevents lost covers during checks
• Opaque cover keeps documents visible without full exposure

Will this holder protect documents from weather and road debris?

Yes. The smoke-colored polycarbonate lid forms a weather-resistant barrier and the ABS base sheds impact and abrasion from road debris. Together they reduce moisture ingress and shield papers from direct sunlight and grime.

• Waterproof sealed cover keeps moisture out
• UV-resistant materials prevent sun damage to papers
• Resistant to salt spray and grime commonly encountered on roads
• Opaque finish minimizes sunlight exposure while keeping contents legible

Who is this for: Fleet operators, independent truckers, trailer rental companies and vehicle maintenance teams who need a dependable, low-profile place to store registration cards and permits. If you mount paperwork on trailers, semi-trailers or service trucks and want a resilient, weatherproof and easy-to-install solution that prevents lost lids and keeps documents legible, this 8-pack from PRINIC is designed for that purpose.
