Nilight LED Light Bar Clamp Kit for Roof Rack & Roll Cage — 8-Count (90021H) Black, Aluminum Vibration-Damping

Nilight Horizontal Bar Clamp Mounting Bracket Kit securely attaches LED light bars to roof racks, roll cages, and bull bars with a vibration-damping rubber insert and durable aluminum alloy construction.

This 8-count pack (model 90021H) supplies four heavy-duty clamp brackets that lift and stabilize horizontal LED light bars on tubing from 1" up to 2" diameter. Designed for off-road rigs, trucks, ATVs and utility vehicles, each bracket is pre-drilled for fast attachment, includes an Allen hex key, and ships with a 2-year warranty for peace of mind. The finish and rubber inserts protect vehicle tubing while reducing vibration and metal-on-metal contact.

How will these clamps hold my LED light bar on a roof rack or roll cage?

The brackets grip round tubes using a contoured aluminum clamp plus a replaceable rubber insert that increases surface contact and prevents slipping. The mounting plate raises the light slightly, creating clearance from the tubing to reduce scratching and improve beam clearance.

• Fits 1", 1-1/2", 1-3/4", and 2" diameter tubes
• Aluminum alloy body for a strong, lightweight hold
• Rubber inserts damp vibration and protect finishes
• Raised mounting plate for added clearance and reduced abrasion

Will these brackets be easy to install on my vehicle?

Yes — each clamp is pre-drilled and designed to accept common LED light bar bolt patterns, so you can install them without modifying your vehicle. The kit includes an Allen hex key, and the clamps bolt around the tubing rather than requiring welding or permanent changes.

• Pre-drilled holes accommodate most light bar hardware
• Allen hex key included for immediate use
• No drilling into vehicle tubing required for most setups
• Simple two-bolt clamping action for quick mounting and removal

How durable are the brackets in off-road conditions?

The clamps are made from a corrosion-resistant aluminum alloy and finished in black to resist the elements and road grit. The rubber insert minimizes direct metal-on-metal wear while helping isolate the light bar from shock and small impacts.

• Aluminum alloy construction resists rust and corrosion
• Black finish for added surface protection and low visibility
• Rubber inserts absorb vibration and reduce abrasion
• Engineered for repeated mounting and removal without deformation

Can one kit handle multiple lights or different tube sizes?

The kit includes four clamps (8 pieces total hardware) which can secure a single long light bar or multiple smaller lights depending on spacing and weight. Because the inserts and clamp profile fit several tube diameters, the same kit works across roof racks, roll cages, and bull bars on a range of vehicles.

• Four brackets included, enough for many single-bar installations
• Compatibility with 1" to 2" tube diameters for broad vehicle coverage
• Pre-drilled plates let you add additional lights without reshaping clamps
• Modular system — add matched brackets for longer bars or multi-light arrays

Who this is for: Off-road enthusiasts, tradespeople, and vehicle owners who need a reliable, non-permanent way to mount horizontal LED light bars to roof racks, roll cages, bull bars, or tubing frames. Choose this Nilight kit if you want corrosion-resistant clamps that protect tubing finishes, absorb vibration, and allow easy installation and adjustment without specialized tools.
