It’s possible that your keys or caster bolts have fallen behind your tool box drawers during shipment. Please remove the bottom drawer of your tool box to see if your keys or bolts fell into the frame. If you still can’t find them, please contact us at

We use high-quality 18-gauge steel, which is thicker and more durable than the more common 20 and 22-gauge steel. This makes our tool boxes a bit heavier, but also sturdier and longer lasting than many other tool boxes on the market today. Paint is applied to our boxes using powder coating technology, which results in a hard finish that’s more durable than conventional paint.

Ball bearing slides contain small metal balls that assist in opening and closing the drawers. Ball bearings roll rather than slide, which reduces friction and makes the drawers easier to open and close. This is an important feature for tool box drawers, which are often used to hold heavy items, as the ball bearing slides allow for effortless drawer movement. We use ball bearing slides as part of the high standard of quality that we hold for all of our products.

This is the amount of weight that we guarantee the slides will be able to hold for 50,000 drawer open and closes. So, a drawer with 100-lb. rated slides on each side will be able to open and close a drawer containing 100 pounds of weight at least 50,000 times. This estimation is conservative to ensure that our products last a lifetime. However, in order to comply with the conditions of the product warranty, we ask that you keep within the pound rating recommendations.

Most of the Viper Tool Storage products come with a limited lifetime warranty “to be free from defects in materials and workmanship for the as long as the original owner owns the product.”

We send orders weighing less than 125 pounds via UPS; when your item is shipped tracking information will be sent to the email address provided during checkout. UPS will ship items that weight up to 150 pounds, but in our experience, they don’t always provide the extra care that a heavy metal tool box requires, so shipments over 125 pounds are sent freight. We use several freight carriers, and which we choose depends on your location and the size and weight of your order. We strive to provide the most affordable shipping possible while ensuring that your items will arrive quickly and safely.

First, identify whether the delivery address is in a commercial or a residential area. If your order is being sent to a business located in a commercial area but does not have a dock, please let us know that you will require lift gate service in the “Comments” field during checkout. Freight deliveries are usually delivered within a 4 hour window; if you must be away from the delivery location during the estimated delivery window, please tell us in the “Comments” section during checkout and we will ask the freight carrier to contact you prior to delivery so that you can make arrangements to be present when the delivery is made. This isn’t a guarantee that they will contact you!

A valid phone number is REQUIRED for freight orders. Freight carriers will contact you directly to schedule delivery. Failure to supply a valid phone number may cause delays in shipping, and you may be additionally charged for storage and/or redelivery charges.

Delivery appointments are available for an additional fee, which varies between carriers, so please contact us if you’d like to pay for this service. Drivers will not take freight to other areas such as back rooms, garages, upper floors, etc. Please do not ask the driver to move your freight to another area unless you are willing to be charged extra for that service.

When your shipment arrives, please inspect the outside for damage thoroughly before signing for it! Any damage should be noted on the delivery receipt. We are not responsible for claims on shipments where damage is not noted on the delivery receipt!

Yes, please do! We’re happy to answer any questions you may have. You can call us from 8am -4:30 (PST) Monday through Friday at (951) 296-1359, or email us
