Rear 1/4 glass opening handle. Porsche 911/912 1965-77

90154304

Product Information

Rear 1/4 glass opening handle.
Provides the lever action to latch, unlatch, and hold the rear quarter glass in the open or closed position, maintaining correct sealing pressure when shut and controlled ventilation when open.

Fits:
Porsche 911/912 1965 - 1977

Diagram ref no 14

• Position: Rear quarter window, left or right (handle is typically side-agnostic)
• Sold each (order two to renew both sides)

Over time, the quarter window handle can become pitted, loose, or seize due to wear, corrosion, or age. A worn handle not only detracts from appearance but can also fail to latch the glass securely, leading to rattles or water ingress.

Replace the handle when:
• The handle feels sloppy, stiff, or seized in operation.
• The window won’t stay latched or won’t hold its open position.
• Performing interior restoration, glass replacement, or seal service.

Installing a fresh handle restores proper latch function, smooth operation, and a clean, factory-correct look to your Porsche’s quarter windows.
