Calvana (2-Pack) Roof Vent Operator

Calvana's 2-pack roof vent operators are direct-fit replacement arms for Jensen JRP1000RC and compatible Heng's vents, providing a durable 6-inch arm for smooth opening and closing of your RV or trailer roof vent.

When a worn or broken vent operator makes ventilating your RV difficult, swapping in a precise replacement restores reliable airflow control. These Calvana operators are engineered to match the mounting pattern and arm length of common Jensen and Heng's models so you can reinstall a functioning crank mechanism without modifying the vent. They come as a two-piece set and omit the crank handle, allowing you to reuse the existing handle or select one that fits your preference.

Will these operators fit my Jensen or Heng's roof vent?

Yes — they are produced to align with the mounting points and motion of Jensen JRP1000RC and many Heng's models like 501.1034. The 6-inch arm length mirrors the original design so the vent opens and closes as intended.

• Exact match to JRP1000RC mounting pattern
• Compatible with Heng's vent series (501.1034 and similar)
• 6-inch arm length replicates original travel distance
• Two operators included for replacing both sides or keeping a spare

How difficult is installation and what tools do I need?

Installation is straightforward for most DIYers: remove the old operator, align the new arm with the vent gearbox, and fasten with the same screws. You won’t need specialized tools beyond common hand tools, and the process typically takes under 30 minutes per operator.

• Basic tools: screwdriver, pliers, possibly a small socket set
• Reuses existing crank handle — no extra parts required unless you choose to replace the handle
• Simple alignment keeps vent travel and sealing consistent
• Two-piece pack lets you do both sides in one session

What materials and durability can I expect?

Calvana operators are built from materials selected for outdoor durability, resisting typical wear from repeated use and exposure. They’re designed to operate smoothly in varying weather conditions for reliable vent control over time.

• Robust construction to withstand regular use
• Corrosion-resistant surfaces for outdoor exposure
• Smooth pivot and arm motion for consistent sealing
• Sold as a pair to reduce future downtime

Does the package include a crank handle or extra hardware?

The package contains two replacement operators only and does not include a crank handle. This allows reuse of your existing handle or choice of a replacement handle separately to match your interior style and length requirements.

• Two operators included; no handle provided
• Compatible with standard Jensen/Heng's crank handles
• Ideal for paired replacements or keeping a spare on hand
• Minimal hardware needed if existing screws and handle are retained

Who is this for: These Calvana vent operators are intended for RV and trailer owners, maintenance technicians, and DIY renovators who need an exact-fit, durable replacement for Jensen JRP1000RC or compatible Heng's vents. Choose this 2-pack if you want to restore smooth opening and closing, replace both sides at once, or keep a backup part that matches factory travel and alignment without modifying your vent system.
