Horizontal Bar Clamp Mounting Bracket Kit for Roof Rack LED Light Bar

In this review the Horizontal Bar Clamp Mounting Bracket Kit is assessed for drivers who want to add an LED light bar to a roof rack or roll cage without drilling. The bottom line: this kit is for owners who need a sturdy, raised mounting solution that protects tubing from scratches and reduces vibration. The build quality and included rubber inserts are the single biggest reasons to buy, since they provide a firm grip and protect the tube surface while lifting the light bar clear of contact points.

Key Features

• Sturdy bracket: Constructed from strong aluminum alloy to keep an LED light bar held firmly in place and resist bending under vibration.
• Raised mounting: Raises the light bar height to avoid scratches on surrounding surfaces and to provide better beam clearance.
• Vibration damping: High quality rubber inserts reduce driving vibration and prevent the metal bracket from scraping the tube surface.
• Wide tube fit: Works with common tube diameters of 1 in, 1-1/2 in, 1-3/4 in and 2 in so it fits most roof racks, bull bars and roll cages.
• Easy installation: Pre-drilled holes and an included Allen hex key let you add lights quickly without drilling into the vehicle.
• Practical pack size: The package includes 4 mounting brackets so small light bars or paired mounts can be assembled right away.

Who It's For

This kit is best for overland and off-road vehicle owners who mount compact to medium LED light bars to roof racks, bull bars, or roll cages and want a non-permanent mounting that protects tubing surfaces. The raised profile suits drivers who need more clearance to avoid stone chips and scratching while off-road or on rough roads.

It is less suitable for drivers who require custom-fit mounts for atypical tube diameters outside the listed range or who need integrated wiring or tilt mechanisms; those users should look for a full light bar mounting system with vehicle-specific fittings.

Pros & Cons

Pros

• Solid aluminum alloy construction gives a reassuringly rigid mount and minimal rattle when tightened properly.
• Rubber inserts protect tube finish and improve grip, reducing movement under load.
• Pre-drilled holes and included Allen key make installation straightforward for most DIYers.
• Compatible with a broad range of tube diameters, increasing versatility across vehicles.

Cons

• Bolt length received mixed feedback from some customers, so very thick accessory tubing or added plates may need different hardware.
• Fit can be mixed on non-standard roll cages; some users may find the inner cuff does not suit every tube finish or profile.

Our Verdict

The Horizontal Bar Clamp Mounting Bracket Kit is a practical, value-oriented choice for DIYers who need a raised, protective mount for LED light bars on common tube sizes.

Frequently Asked Questions

Will these clamps fit a 1-1/4 in tube?
They are designed for 1 in, 1-1/2 in, 1-3/4 in and 2 in tubes, so a 1-1/4 in tube falls between sizes and may not clamp securely.

Are rubber inserts replaceable?
The kit includes high quality rubber inserts for protection; replacement inserts are not provided but similar rubber padding can be used if needed.

Do I need to drill holes in my rack?
No drilling is required for the bracket attachment since it uses pre-drilled holes and comes with an Allen hex key for installation.
