The Weather Guard 11921-52-01 cargo stops are adjustable rests that help hold ladders, pipe and long materials on top of your Weather Guard aluminum headache rack. They give your load something to sit against so it does not slide side to side while you drive. This is a 2-pack of aluminum stops in a black ARMOR TUF finish, and each one slides along the length of the rack and locks in place with a knob, so you can set the spacing to match your load without any tools. They fit only the Weather Guard aluminum modular headache racks (11902-52-01 Open Frame, 11908-52-01 Half Bar, 11904-52-01 Louvered and 11906-52-01 Hex) and not the older steel Protect-A-Rail cab protectors.
What's Included:
Two aluminum cargo stops (one 2-pack)
Adjustment knob on each stop for tool-free positioning along the rack
Features
Holds Ladders and Long Loads in Place The cargo stops give ladders, pipe and long material a solid edge to rest against on top of the rack, so your load stays put instead of shifting across the bars. They add a simple point of support that makes tying down long items easier and more secure.
Slide and Lock, No Tools Needed Each stop slides along the length of the rack and locks down with a knob, so you can loosen it, move it to match your load, and snug it back up by hand. There is no drilling and no wrench needed to reposition them.
Sold as a 2-Pack You get two matching stops in the box, so you can set one on each side of a load and pin it in place. Two stops cover most ladder and lumber setups right out of the package.
Aluminum With a Black ARMOR TUF Finish The stops are made of corrosion-resistant aluminum with a black ARMOR TUF powder coat, so they stand up to weather and daily loading and match the black finish of the rack while keeping the added weight low.

Frequently Asked Questions
Straight answers on specs, fit and support
What do the cargo stops do?
They give ladders, pipe and long materials a solid edge to rest against on top of the rack so the load does not slide side to side while you drive. They are a support and positioning accessory for the rack.
How do they adjust?
Each stop slides along the length of the rack and locks in place with a knob you turn by hand. Loosen the knob to move a stop, then tighten it back down. No tools and no drilling are needed.
How many come in a pack?
Two. They are sold as a 2-pack, so you can set one on each side of your load right out of the box.
Do the cargo stops strap my load down for me?
No. They help position and retain a load so it does not shift, but you still need to strap or tie your cargo down properly. Use them together with your tie-downs, not in place of them.
Which racks do they fit?
They fit the four Weather Guard aluminum modular headache racks: the 11902-52-01 Open Frame, 11908-52-01 Half Bar, 11904-52-01 Louvered and 11906-52-01 Hex. They do not fit the older steel Protect-A-Rail cab protectors.
What are they made of?
Corrosion-resistant aluminum with a black ARMOR TUF powder coat, so they hold up to weather and daily loading and match the black finish of the rack. They are backed by a Weather Guard Limited Lifetime Warranty.
