Kayak Blocks


Darby foam kayak blocks provide extra security and stability to your Extend-A-Truck setup, eliminating tilting and swaying of loads while driving.


Darby Industries manufactures sturdy, non-scratch foam kayak blocks that resemble steel I-beams. For example, the kayak blocks can be placed across the extension’s top crossbar to offer more functionality and stabilization.  This creates a safe and secure cradle while driving so there is no tilting or swaying. The wide cutout on the bottom of the block allows it to fit securely over the crossbar. While the kayak blocks were designed to be used with the Turbo Rack and Extenda-A-Truck, their universal fit means that they accommodate almost any roof rack bar on the market.

The Extend-A-Truck is an economical cargo management solution that is easy to use, easy to adjust, and easy to remove. Various extensions and a 350-lb. load capacity ensure it can accommodate almost any kayak or canoe. 

Darby Industries stands behind its product with a 1 Year Manufacturer’s Warranty. If you have questions, concerns, or just want to submit a product review, please contact us and speak with the company’s president directly.
