Zonon rooftop tent mounting hardware 28-piece kit — black steel & aluminum clamps for crossbars, easy single-wrench installation

Zonon 28-piece rooftop tent mounting hardware is a complete black bracket kit that secures your rooftop tent to most crossbars and roof racks.

This kit is a ready-to-use set of metal brackets, blocks, screws and nuts designed to mount a rooftop tent and related accessories. The 28 included components combine stainless-like black steel blocks, aluminum spacer pieces, and machine screws so you have matched hardware for a tidy, repeatable installation. It’s intended to work with factory crossbars and many aftermarket rack systems—refer to the sizing chart before purchasing to confirm fit.

How does this kit attach a rooftop tent to crossbars?

The kit uses clamping blocks that sandwich the vehicle crossbar and threaded fasteners to draw the assembly tight. Four long black steel blocks sit on top of the crossbar while the aluminum blocks and nuts tighten underneath, creating a secure sandwich clamp that transfers the tent load to the roof rails.

• Includes four 5.31 x 1 inch black steel blocks to sit above crossbars.
• Four 2 x 1.18 inch aluminum blocks act as lower spacers and load distributors.
• Eight 3-inch screws and eight matching nuts provide the clamping force.
• Standardized thread sizes let you use a single wrench for installation.

Will these brackets fit my roof rack or crossbar profile?

The design targets common crossbar shapes used on most vehicles, including many factory and aftermarket bars. Because crossbar dimensions vary, check the provided size chart and compare block footprints and bolt clearance with your bars before buying.

• Compatible with many original equipment and modified roof racks.
• Blocks and screws allow for small positional adjustments during fit-up.
• Not vehicle-specific—measure bar width and height against the chart.
• Supports accessory attachments like awnings and side tents through the same interface.

What materials and durability can I expect from the hardware?

The kit combines heavy-duty black-finish steel blocks with aluminum spacer blocks to balance strength and corrosion resistance. The materials are chosen to resist deformation under load and to hold up to outdoor exposure on camping trips, though routine inspection and correct torque are recommended.

• Black steel blocks for high hardness and load-bearing capacity.
• Aluminum spacer blocks reduce weight and resist corrosion.
• Machine screws and nuts sized for repeatable clamping strength.
• Finish helps protect against weathering and abrasion in normal use.

How easy is installation and what tools do I need?

Installation is straightforward and requires only a single wrench to tighten the kit’s screws and nuts. The assembly sequence resembles mounting a roof rack accessory: position blocks, thread screws, and tighten to secure the tent base.

• No special tools required—one standard wrench is sufficient.
• Simple step-by-step clamp assembly—ideal for two people.
• Quick removal and reinstallation for seasonal use or storage.
• Can be combined with other rooftop accessories using the same mounting points.

Who this is for: Outdoor enthusiasts who own a rooftop tent or plan to add one and need a complete, versatile mounting hardware set; vehicle owners with standard crossbars who want a durable black-finish bracket system for tent bases, awnings, or side tents. If you need vehicle-specific fitment, measure your crossbars and compare to the size chart before ordering.
