"Keep your truck bed cargo organized and secured in place with the Apex Adjustable Pickup Truck Cargo Bar. The adjustable bar has grooved rubber ends to grip the truck bed and an easy-to-use ratchet to lock the bar tightly in place. The cargo bar also works great as an extra tie-down area and includes pre-drilled holes for optional permanent mounting. Fits all pickup truck beds from 40"" to 70"" wide. Grips to the pickup truck bed with two 2.25"" wide by 3"" long by 3/8"" thick grooved rubber ends designed to prevent the cargo bar from slipping inadvertently and potentially causing cargo shifting. Each rubber end pivots in a variety of positions for adapting to most surface angles."
