CIPA COMP II Marine Clamp-On Mirror 4" x 11" Black — No-Drill, Adjustable Pivot for Boats & ATVs

The CIPA 11083 COMP II Black 4" x 11" Marine Mirror is a clamp-on, no-drill adjustable side/rearview mirror designed for boats, ATVs and trailers that need a wide field of vision.

Built by CIPA, a longstanding supplier to automotive, powersports and towing industries, this COMP II ski-style mirror combines a 4" x 11" rectangular glass surface with a pivot cup-mount bracket for broad, customizable sightlines. The clam-shell clamp attaches to most windshield trims and edges without drilling, making it a fast, non-destructive retrofit for marine and off-road vehicles that require improved visibility while towing, navigating tight spaces, or reversing.

How does the pivot cup-mount bracket improve adjustability?

The pivot cup-mount bracket offers more than 120 degrees of movement so you can fine-tune the mirror angle quickly from a seated position. It was designed to withstand vibration and maintain position once set, reducing constant readjustment on rough terrain or choppy water.

• Over 120° of adjustment for wide horizontal and vertical coverage
• Secure pivot mechanism holds set angle under vibration
• Easy reach adjustments without tools
• Works for drivers and passengers due to wide pivot range

Will this mirror fit my windshield trim or mounting point?

The mirror uses a clam-shell clamp design that fits most common windshield trims and glass edges, so it often installs without modification. Because no drilling is required, it’s ideal for renters, leased vehicles, or owners who want a reversible installation.

• Clam-shell clamp fits standard windshield trims and edges
• No-drill installation preserves factory surfaces
• Adjustable clamp tension to accommodate varying thicknesses
• Compact footprint works on boats, trailers and off-road cabs

What are the mirror’s size and durability features?

The CIPA COMP II mirror uses a 4" x 11" rectangular glass that balances a broad field of view with a slim profile to reduce wind resistance and obstruction. Materials and construction are intended for automotive and marine environments, offering corrosion-resistant components and a finish that tolerates outdoor exposure.

• 4" x 11" glass for extended lateral viewing area
• Black finish resists visual glare and complements most vehicles
• Durable mounting components suited for marine/powersports use
• Compact design reduces interference with handling and sightlines

How simple is the installation and maintenance?

Installation is straightforward: clamp the mirror on the desired trim, tighten the clam-shell, then position the pivot to the preferred angle. Maintenance is minimal—periodic cleaning of the glass and light inspection of the clamp and pivot for corrosion or loosening will keep the mirror functioning reliably.

• Tool-free clamp attachment—no drilling required
• Quick angle adjustments via pivot cup mechanism
• Routine cleaning with mild soap and water preserves clarity
• Inspect and re-tension clamp periodically for secure fit

Who is this for: The CIPA 11083 COMP II Black 4" x 11" Marine Mirror is aimed at boat owners, tow vehicle drivers, ATV and UTV operators, and anyone needing a durable, adjustable aftermarket mirror without altering their vehicle. It’s particularly useful for those who want a reversible, no-drill solution that offers a large viewing area and dependable hold in vibration-prone environments.
