Truck, tonneau cover, rack, toolbox, straps and unrelated accessories are not included unless expressly stated.
ACCESS and related Agri-Cover product families are engineered around truck-specific bed dimensions, practical cargo access and serviceable mounting systems. The B1020039 should be selected by its exact application rather than by brand name alone.
What is the B1020039?
It is the ACCESS folding hard tonneau cover described in this listing for the stated truck, bed, cover or rack application.
How do I confirm fitment?
Match the exact year, make, model, bed length and every factory-equipment qualifier shown in the title and fitment table.
Will it fit another bed length?
Do not assume it will. Different box lengths normally require different cover, rail, rack, mat or seal dimensions.
Are factory rail or storage systems important?
Yes. Deck rails, RamBox, CarbonPro, bedside storage, toolboxes and other bed equipment can change compatibility.
Is installation hardware included?
Only the components packaged by the manufacturer for this exact listing are included. Unlisted racks, covers, straps and accessories are separate.
Is professional installation required?
Many applications are designed for owner installation, but professional help is recommended whenever drilling, complex alignment or load-bearing rack setup is involved.
Is the truck bed completely waterproof after installation?
No truck-bed cover or seal should be treated as a guarantee of a completely watertight compartment. Correct alignment and seal contact help manage weather exposure.
Can Black Ops Auto Works help verify the application?
Yes. Send the complete vehicle, measured bed length and details about factory rails, storage boxes, toolboxes, racks or existing covers before ordering.

Flares and Wheel-Well Protection Fender flares must match actual front and rear body contours, bed configuration and attachment.

Find Chevrolet Silverado parts for a complete accessory plan with full model, body designation and duty class established. Match cargo protection, auxiliary lighting and chassis-support components to the actual truck. Lighting Pattern and Installation Compare beam distribution for the intended use rather than brightness alone. A narrow spot and a wider driving/combo pattern serve different coverage needs; use the manufacturer’s guidance for the specific light. Check whether the purchase is a single pod, light bar or complete package. Mounting brackets, wiring, controls and electrical requirements need their own contents and compatibility review. Cargo Protection and Chassis Support Bed mats and flares require actual bed length, liner arrangement, body contours and trim. Confirm attachment and clearance with covers, racks or other installed equipment. Air-helper springs require exact chassis, axle, spring layout and brackets.
