The Classic Platinum is custom designed and will fit your truck bed perfectly.

Also featuring a tough vinyl tarp that has anti-curl corners along with a thick polymer backing. The Extang Classic Platinum provides extreme protection for your truck bed in all weather conditions. Not to mention, they ward off unwanted visitors. Out of sight, out of mind!

The no-drill, TuffKlamps have two settings for the support bows. the HIGH position helps shed the most water, as well as keep the cover tight in hotter cimates. The LOW position is used for colder climates. The support bows are also made from anodized aluminum to match the looks and durability of the frame. For easy and secure operation, the supports bows are spring loaded on the ends. Extang backs this cover with a lifetime warranty on the frame, and a 10 year warranty on the vinyl.

Frequently Asked Questions

Will they work with bed liners?
Yes, but there are a few simple additional steps that need to take place to make them compatible. If you own an under the rail liner, you need a couple small rubber shims to assist the lifting of the tonneau over the tailgate protector. Over the rail bed liners need to be notched out in order for the tonneau clamps to go through.
Will I be able to open and close my tailgate?
YES, there is no restriction caused by the tonneau.
What can I clean my tonneau with?
We recommend using soapy water with a medium bristle brush. Extang also makes a tonno cleaner that is ideal for the cleansing process.

Limited Lifetime Warranty on Frame / 10 Year Warranty on Vinyl

WARRANTY DURATIONLifetime Frame: Extang offers a lifetime warranty against defective materials or workmanship on all tonno rails, aluminum components, clamps, bows, hardware. 10 Year Tarp: Extang offers a 10 year warranty against defective materials or workmanship on the vinyl covering. The 10 year warranty coverage is as follows:

WARRANTY CONDITIONS: This warranty is against defective materials or workmanship. The warranty is void if the product has been damaged by accident, unreasonable use, neglect, improper service/installation/removal, modifications, acts of God, normal wear and tear, or other causes not arising out of defective materials or workmanship. Consequential and incidental damages are not covered under this warranty.

THE FOLLOWING CONDITIONS WILL ALSO VOID THE WARRANTY: Wind whip damage: Tarps must be secured at all points when vehicle is in motion. An unsecured tarp will flap, resulting in damage to the fabric.

Improper cleaning: Recommended to use the tested and approved Extang Tonno Tonic™ or clean with soap and water only. Do not use vinyl conditioners (i.e. Armor All®) because they will shrink the vinyl.

Overloading of cargo: Cargo should not touch the tonno at any point. Protrusions in the tarp will stress the fabric. Cargo may shift while traveling and cause it to push against the fabric and damage it.

The warranty applies to the original consumer/purchaser and for the truck on which the tonno was originally installed and shall not apply if the product has been removed from the original vehicle.

Warranty registration must be on file and/or proof of original purchase (detailed and dated receipt) required for warranty to be effective. Warranty coverage starts from the date of purchase.

PERFORMANCE: Provided all warranty conditions are met Extang will either repair or replace (at Extang’s option) the product or component. Extang may require the original item to be returned postage prepaid for final determination. Extang reserves the right to substitute and offer the respective warranty discount on an entire replacement system or provide other remedies than those listed in this warranty for discontinued products or other reasons. A return authorization number must be obtained from our customer service department prior to returning any product. Shipping charges will apply for any repair or replacement. This warranty gives you specific legal rights and you may also have other legal rights which vary from state to state.
