What is your Return Policy?

At Northgrid Supply, we want every customer to shop with confidence. If something doesn’t go as planned, we’ve made returns and refunds simple and fair. Here’s how it works:

1. Return Window

You can request a return within 30 days of receiving your order. Unfortunately, we’re unable to accept returns after that time frame.

2. Who Pays for Return Shipping?

  • If your item arrives damaged, defective, or incorrect, we’ll cover the return shipping cost.
  • If you’re returning an item because you changed your mind, you’ll be responsible for return shipping fees.

3. Damaged or Defective Items

Received something broken or not working properly? Contact us within 30 days. We’ll provide a prepaid return label and once the item is returned and inspected, we’ll issue either a full refund or a replacement—including any original shipping costs.

4. Changed Your Mind?

If you no longer want the item, you can return it within 30 days—as long as it's unused, in its original packaging, and in resellable condition. You’ll need to handle the return shipping, and once we receive and inspect it, we’ll refund the product cost (excluding shipping).

5. Refund Processing

Once we receive and approve your return, we’ll send a confirmation email and issue a refund to your original payment method within 7 business days. Please allow additional time for banks or credit card companies to process and reflect the refund.

If it’s been over 10 business days since your refund was approved and you still don’t see it, contact us at support@northgridsupply.com and we’ll look into it immediately.

6. Restocking Fees

In some cases, a restocking fee may apply depending on the item and return reason. If applicable, we’ll clearly communicate this during your return request process.

The Estate Below Ground Tornado Shelter is designed for installation in a yard or field outside a home or building. Its underground configuration combines a powder-coated finish with an entry stairway and interior seating for residential severe-weather protection.

Available in Estate and Estate Max configurations, the shelter provides bench seating on three sides and accommodates either 10 or 16 occupants depending on the selected size. A steel handrail and non-slip stair treads provide additional convenience when entering from the surface.

Installation requires excavation and proper site preparation. Professional installation by an NSSA-accredited installer is recommended and required to certify the shelter with an NSSA Type 4 Seal.

Key Features

  • Below-Ground Installation: Designed for exterior installation in a yard or field.
  • Powder-Coated Finish: Provides protection against rust and corrosion.
  • Three-Sided Bench Seating: Interior bench seating is provided on three sides of the shelter.
  • Surface Stairway Entry: Uses a stairway for access from the surface.
  • Steel Handrail: Provides a handrail along the stairway for added support.
  • Non-Slip Stair Treads: Stair treads are designed to provide additional safety and convenience during entry.
