PRINIC Trailer Document Holder 2-Pack, Opaque Gray ABS with Smoke Polycarbonate Lid and Wire-Tether

These document boxes are designed to keep vehicle papers readable and dry on trailers, trucks, and semi-trailers. Each kit combines a durable ABS body with a clear, smoke-tinted polycarbonate lid that snaps closed and stays attached with a spring-mounted cover. The compact footprint fits most license-plate and trailer mounting locations while resisting impact, corrosion, and UV exposure so your documents remain protected in demanding transport conditions.

How big is this document holder and will a standard registration fit?

The holder's exterior measures 6" x 5" x 2", while the internal cavity is approximately 3-3/4" in diameter and 1" deep, sized to accommodate folded or rolled copies of registration cards and small certificates. It works well for common trailer paperwork but is not intended for large-format documents without folding.

• External footprint: 6 x 5 x 2 inches for compact mounting
• Internal space: ~3.75-inch diameter by 1-inch depth
• Accepts folded or rolled registration cards and small papers

What materials protect the papers from weather and wear?

The housing uses impact- and corrosion-resistant ABS plastic while the lid is made from polycarbonate, a clear, durable plastic that tolerates UV exposure. The smoke-colored cover seals against moisture and is retained to the base by a spring mechanism, helping prevent loss and keeping contents readable through the lid.

• ABS body for toughness and chemical resistance
• Polycarbonate lid for clarity and UV durability
• Spring-secured, smoke-tinted cover provides a moisture barrier

How simple is installation and where can it be mounted?

Installation is straightforward with standard hardware and mounting points suitable for trailers, semi-trailers, trucks, and similar equipment. The design keeps the lid attached so the cover won’t get misplaced during road checks or maintenance.

• Quick-mount friendly for trailer and truck exteriors
• Wire-attached cover prevents loss while open
• Low-profile shape fits near plates, hitches, or side panels

How durable is the kit for long-term outdoor use?

Built to withstand transportation environments, the kit resists impact, salt, and sunlight to protect documents over time. The materials and sealing approach reduce moisture ingress and fading so papers stay legible even after repeated exposure to the elements.

• Corrosion-resistant construction for salty or humid conditions
• Impact-resistant plastics reduce cracking or breakage
• Smoke cover and polycarbonate lid help prevent UV-related fading

Who this is for: drivers, fleet managers, and trailer owners who need a compact, weather-resistant place to store registration cards and small documents on the outside of trucks and trailers. If you want a simple, economical way to keep essential paperwork visible, protected, and attached to the vehicle, this PRINIC 2-pack delivers durable materials and an easy-install form factor without taking up much space.
