Overview

The Vaultz VZ00355 fills a specific gap between flimsy storage boxes and expensive heavy-duty safes. It's built for people who need to secure a meaningful volume of valuables — clothing, electronics, documents, or gear — in environments where they can't control who has access to the space. Dorm rooms, shared barracks, camp bunks, and guest rooms are all scenarios where a locked trunk makes sense, and the 31-gallon capacity means you're not choosing between security and storage space. The dual key locks are the headline feature: two separate locking points mean a single compromised latch doesn't expose everything inside.

Construction-wise, Vaultz hasn't cut corners at the corners — literally. The chrome-steel reinforcements at each edge protect the most impact-prone spots and give the trunk a noticeably sturdier feel than plastic-cornered competitors. Metal support rails run along the body for additional rigidity. The built-in wheels and handle keep mobility practical; this isn't a trunk you'll want to lift and carry when loaded, but rolling it between rooms or down a hallway is straightforward. The single interior compartment keeps things simple — bring your own organizers if you want to separate small items — and the black finish looks clean and professional in most settings, though it does show wear over time.

Frequently Asked Questions

The VZ00355 uses dual combination key locks — Vaultz's trademarked locking mechanism — meaning you get two separate lock points for redundant security. Keys are included with the trunk.
The trunk measures 29.25"L x 15.25"W x 11.5"H and holds up to 31 gallons. That's enough room for folded clothing, a laptop, documents, electronics, and other bulky personal items — it's genuinely extra-large compared to most lockboxes.
It has built-in wheels and a handle, so rolling it around a room or down a hallway is manageable. That said, the maximum weight recommendation is 23 pounds, so it's designed for moderate loads rather than truly heavy cargo.
They're structural — the chrome-steel corners reinforce the points most vulnerable to impact and rough handling, which makes a meaningful difference if the trunk gets bumped during transport or stacked in storage.
It's primarily an indoor and institutional storage solution — bedrooms, dorms, military barracks, and camps are the stated use cases. The wheels and latch closure aren't weatherproofed, so prolonged outdoor exposure isn't recommended.
