Andersen 7191 RH Operator

The 7191 RH Operator delivers direct-fit replacement for 1974-1989 Andersen casement windows — no drilling, no modifications, no callbacks. Uses existing mounting holes with standard screwdriver installation. With a perfect 5.0 rating across 31 reviews citing “easy installation”, it’s the operator that saves contractors from compatibility headaches.

This operator targets a specific niche: Andersen Perma-Shield Casement windows manufactured between 1974 and 1989. If the existing operator shows stamps 7198-17, 1818-2, 7191, or 7191-2, this replacement drops right in.

Compatibility That Actually Matters

Getting the wrong operator means a callback. Here’s what matches:

Specification	Value
Arm Length	9-3/8 inches (most common)
Visible Glass Width	19-3/4” or 24”
Handing	Right-Hand (lock on right from interior)
Window Series	Perma-Shield Casement (Wood)
Manufacturing Years	1974-1989

The part replaces operators stamped 7198-17, 1818-2, 7191, or 7191-2 on the back. Check that stamp first — it’s the quickest way to confirm compatibility.

Built for Montana’s Temperature Swings

The corrosion-resistant metal arm handles exterior exposure without rusting. That matters when temperatures swing from -30°F to 90°F annually. The nylon shoe (stone-colored or black) reduces friction and wear — critical when freeze-thaw cycles put stress on moving parts.

The stone-colored finish matches the original aesthetics of these vintage windows. No bright chrome or modern black to clash with 1970s-1980s architecture.

Installation Without Drama

DIY-friendly installation requires only a standard screwdriver. The process:

1. Remove existing operator screws and detach the old arm
2. Align the new 7191-32 operator with existing mounting holes
3. Secure the operator with provided screws
4. Attach the nylon shoe to the arm and secure with the cover
5. Attach the handle (sold separately) and test operation

The operator includes mounting screws, nylon shoe, and stone-colored cover. Handles and operator channels sell separately.

The Bottom Line

This operator offers a cost-effective solution compared to a service call for a stuck window. For contractors maintaining Montana’s aging housing stock — especially homes from the 1970s-1980s building boom — having the right replacement operator prevents callbacks.

The 7191-32 is the modern replacement for the discontinued 7191-2 (1974-1979). Same fit, upgraded materials. For left-hand windows, the LH version (Part #1361124 or 39-150) provides mirror-image functionality.

Not every window needs replacement. Sometimes the right operator brings 40-year-old casements back to smooth operation.

FAQ

What’s the difference between right-hand and left-hand operators?

Right-hand (RH) means the lock is on the right side when viewed from the interior. Check your lock position before ordering.

Will this work on newer Andersen windows?

No. Newer Andersen series (A-Series, 400 Series) use different operators with different mounting patterns. This operator specifically fits 1974-1989 Perma-Shield models.

What’s included with the operator?

The kit includes the right-hand straight-arm operator assembly, nylon shoe (black or stone-colored), stone-colored cover, and mounting screws. Handles and operator channels are sold separately.

How do I know if this fits my window?

Check for stamps 7198-17, 1818-2, 7191, or 7191-2 on your existing operator. Also verify your window is 19-3/4” or 24” visible glass width and manufactured between 1974-1989.
