    Compatibility

    Designed For Check Before Ordering

    • Custom brackets and accessories

    • DIY fabrication projects
    • Non-round tubing
    • Accessories requiring specialized mounting systems
    • Setups with limited clearance

    What’s Included

    1, 2, 3, or 4 DIY Clamps
    Based on selected quantity
    Stainless Clamp Bolt
    Included with each clamp
    Made in USA
    Machined in-house from black anodized aluminum

    Before Ordering

    1. Measure your rack tubing
    Use calipers or our printable measurement tool to confirm your tube diameter before selecting a size.
    2. Confirm your accessory mounting
    These clamps include 5/16-18 threaded holes on both sides but do not include mounting brackets, accessory plates, or accessory hardware.
    3. Select the matching rack diameter
    Choose the clamp size that matches your actual roof rack tubing. A slightly oversized reading is normal on powder coated racks, so a 1.75" clamp may be correct even if your rack measures slightly over 1.75".

    Common reference sizes: 4Runner TRD Pro 2019–2024, FJ Cruiser 2007-2014, and Sequoia TRD Pro 2020–2022 roof racks typically use 1.75" tubing. GOBI Toyota roof racks typically use 1.00" tubing.
    4. Check clearance
    Confirm your planned accessory will clear your rack, vehicle, rooftop tent, and surrounding components.

    Installation

    1. Position the clamp
    Place the clamp where your accessory, bracket, or custom project will be mounted.
    2. Tighten the clamp evenly
    Using a 1/4" Allen wrench, gradually tighten each bolt a little at a time. Alternate between bolts instead of fully tightening one side first so the clamp seats evenly around the tubing. Visible thread should remain when properly installed.
    3. Attach your accessory
    Use the 5/16-18 threaded holes to mount your own brackets, panels, lights, tools, or accessories. Confirm all hardware is secure before travel.

    Mounting brackets, accessories, panels, lights, tools, and customer project parts are not included. Periodically check and tighten hardware after off-road use or long trips.

    Shipping

    Order Processing: Most in-stock orders ship from Florida within 1–3 business days, with many orders shipping the same or next business day when ordered before carrier pickup.

    Tracking Information: Tracking information is automatically emailed once your order has shipped. Receiving a tracking number does not necessarily mean the package was picked up by the carrier that same day.

    Need It Faster?: We can often arrange upgraded shipping options such as UPS Next Day Air or 2nd Day Air for an additional charge, depending on inventory and carrier pickup schedules.

    Shipping Terms: Once a package has been accepted and scanned by the carrier, delivery times and package handling are outside of our control. If a package is lost or damaged during transit, we will assist with filing a carrier claim when applicable. Packages marked as delivered by the carrier are considered fulfilled.

    International Orders: International customers are responsible for any customs duties, taxes, import fees, or other charges imposed by their country.
