MDI is hosted by Yahoo! Store. Yahoo! hosts the store pages, ordering system, and order data. Yahoo! automatically collects order information but may only use this information in the aggregate. If you accessed this store through Yahoo! Shopping, Yahoo! also automatically collects information about your shopping experience. Please see the Yahoo! Privacy Policy for more information about how Yahoo! uses this information.

All of our sales are facilitated via a secure server (256 bit ssl v2/v3) via our website, which is hosted by Yahoo!, the most trusted source in Ecommerce.  Acceptable forms of payment are Visa, MasterCard, American Express and Discover.  Sorry, no COD's, no money orders and no checks. 

Three very important points not to forget when shipping is considered:
1.        Delivery occurs only on business days, Monday through Friday.
2.        Weekends, holidays or the day of pick-up are not considered transit time.
3.      We will not ship product to a residential address unless that address is also the billing address.  Therefore, if your billing address differs from the shipping address, the shipping address MUST be a commercial address.

As long as we have the products in stock, your order will leave our warehouse within 1-2 business days. In most cases it will take 2-8 business days to arrive (depending on the destination and shipping option) from the day your order is shipped, NOT from the day your order is placed.  Saturdays, Sundays and Holidays are NOT considered business days.


For all orders:  The customer is responsible for receipt of items shipped from our warehouse.  If we receive a package back from the shipper because time has passed and delivery was not coordinated by the customer, we will contact the buyer of the order for payment on re-shipment at your expense (based on shipping method and current pricing as posted on our site) with an additional $15 handling charge.  


All goods are invoiced F.O.B. point of origin.  The products become the property of the Buyer, who assumes the risk, loss or damage in transit at the time material ships-out from the point of origin.  It is at the discretion and expense of MDI to change carriers as we see-fit on a per order basis.  The customer will not be charged any additional shipping or handling charges beyond the amount which appears on their order at check-out.


You are required to inspect all product(s) received at time of receipt.  Claims made due to errors, damage, shortages or non-conformance of products listed must be made within 24 hours of receipt of material.  MDI Supply will not recognize any claims involving third party shipments.


In the event of your failure or omission to send us a notification of claimed
weight or number discrepancy, or of any claimed breach of warranty, it will be conclusive between us that the materials delivered to you were properly delivered as to quantity, number or weight and in conformance with descriptions and warranties, if any.



Any order $1,000 (product amount) or more is not returnable (in part or whole).


Any door with a Dead Lock Prep or a Frame with a Dead Lock Strike Prep is not returnable.


Fire Labeled Doors & Frames are not returnable.


Electrified Hardware items are not returnable.

All orders are subject to inventory availability verification. There may be cases where you have been able to order a product from our site and we will run out of stock before we can update the site and make the product "Currently out of stock."  In the event of this case, our customer service department will contact you to notify you, and ask if you would like to wait for the order to become available, or to cancel your order with us. You may also have the other products from your order shipped separately, and we will send the backordered item when it arrives at our warehouse.  We will always do our best to make sure our customers receive their orders in a timely fashion.


Occasionally our warehouses will run out of stock on certain items.  If you have purchased a product that has run out, our customer service department will contact you via e-mail or phone to ask if you would like to wait for the item to come in, or to remove this item from your order. You will not be charged for items that do not ship to you, however if you choose to have the items shipped separately, there may be additional shipping charges added. If you have any questions about a backorder, please contact us at:
