Prime Line Products H 3557 Jalousie Window Operator

Product Description

The PRIME LINE PRODUCTS H 3557 is a jalousie window operator designed for use in louvered jalousie-style window assemblies. This operator drives the mechanical linkage that opens and closes the glass slats, providing manual control over ventilation and light in residential and light commercial applications. The unit features a reversible design with three link arms, allowing it to accommodate different window configurations from a single part. The aluminum finish provides corrosion resistance suitable for humid or coastal environments. Installation is typically performed by glaziers, window service technicians, or experienced maintenance personnel.

This operator is suited for jalousie window frames found in residential homes, screened enclosures, sunrooms, and light commercial buildings. The reversible mechanism means a single unit can serve both left-hand and right-hand operator positions, reducing the need to stock separate handed parts. The three-arm linkage design distributes force evenly across the slat span, supporting smooth and consistent operation across the full range of louver movement.

Key Features

• Reversible design fits both left-hand and right-hand window operator positions
• Three link arms provide even force distribution across jalousie slats
• Aluminum finish resists corrosion in humid and coastal environments
• Sold in a package quantity of 6 units, suitable for multi-window service calls

Compatibility

Designed as an OEM-style replacement operator for residential and light commercial jalousie window assemblies requiring a reversible three-arm crank mechanism.

Installation Notes

Installation is performed by a qualified glazier or window service technician. Disengage any existing linkage and remove the old operator before fitting the replacement unit. The reversible design should be oriented according to the specific hand of the window before securing fasteners. Refer to local building codes for any requirements governing window hardware replacement in occupied structures.
