Why Choose Vandal Stop?
Competitor models, such as those from Bobrick or Bradley, often use 16- or 18-gauge steel and offer limited warranties. Vandal Stop enclosures feature true 12-gauge construction and the only 10-year vandalism warranty in the industry. When security, longevity, and reliability matter — Vandal Stop leads the way.

Supply Chain
Due to increased demand, more time be required for production. If you have a critical delivery date requirement, please call or email to verify lead times prior to placing an order.
Stocked Items
For certain items that we sell often, we do our best to either keep inventory on the shelf or keep a constant production cue going. For items that are considered "stocked" we will generally be able to ship within 5 business days or less.
Why Are Stocked Items More Expensive?
We're adapting to your needs! While we specialize in made-to-order products, we recognize the growing demand for immediate availability. Adjusting to this requires foresight in demand anticipation, material procurement, initiating stock production, and warehousing—all incurring additional costs. Consequently, our stocked items are priced to reflect these overheads. For customers who can accommodate a production lead time, we're pleased to offer discounted pricing as a thank you for your flexibility.
Billing
Credit Card orders will be charged at the time of checkout. If you wish to be billed when your order ships, you can use the "Pay by Purchase Order" option on the payment section of checkout. You will be asked to upload a PDF copy of your Purchase Order along with a reseller certificate of tax exempt status is applicable. We will invoice you once your order has been shipped.
