Prime Line Products H 3517 Bronze Casement Window Operator

Product Description

The PRIME LINE PRODUCTS H 3517 is a right-hand, bronze-finish metal casement window operator designed for crank-style casement windows. The unit features a 9-inch arm with a square body profile and a 3/8-inch spline drive. The diecast housing encloses a steel worm gear mechanism, delivering durable operation under repeated use. This operator is intended for replacement installations in residential and light commercial applications and is typically installed by window service technicians, general contractors, or experienced DIYers performing window hardware retrofits.

This operator fits most casement window replacement scenarios where the original hardware shares a square body style and 3/8-inch spline specification. Handing is determined by the hinge location of the window as viewed from the outside. The right-hand designation applies when the hinge is on the right side when observed from the exterior. The bronze finish coordinates with common hardware finishes found on older and traditional-style window frames. Package quantity is 6 units per case.

Key Features

• Right-hand operation for windows with right-side hinge placement viewed from outside
• 9-inch arm length with square body type for broad replacement compatibility
• 3/8-inch spline drive fits common casement operator mounting configurations
• Diecast housing provides structural rigidity and corrosion resistance
• Steel worm gear delivers mechanical advantage and long service life
• Bronze finish for aesthetic match with traditional window hardware

Compatibility

Designed as a replacement-fit casement window operator for most standard applications using a square body style with a 3/8-inch spline. Specific OEM window brand compatibility should be verified against the existing operator dimensions and spline size before installation.

Installation Notes

Shut the window completely and confirm no load is on the operator arm before removing the old unit. Window hardware replacement typically requires a screwdriver and may involve removing interior trim to access mounting fasteners. Verify handing by observing hinge location from the exterior prior to ordering. Follow local building codes where applicable for window hardware replacement in commercial or rental properties.
