Prime Line Products H 3539 Casement Window Lock Handle

Product Description

The PRIME LINE PRODUCTS H 3539 is an aluminum casement window locking handle designed as a direct replacement for standard casement window hardware. The die-cast aluminum construction provides durable operation and a secure lock engagement. The handle is non-handed, meaning it installs on both left- and right-hand casement windows without requiring a separate part. It also accepts a 1/8 inch security pin for added tamper resistance. This part is typically installed by glaziers, general contractors, property maintenance technicians, or experienced DIYers performing window hardware replacement.

This casement window locking handle suits residential and light commercial applications where a standard casement operator and locking handle are required. Its non-handed design makes it a practical stock item for maintenance crews managing multiple window units across a property. The security pin acceptance adds an optional layer of locking security for windows requiring restricted access.

Installation Notes

Installation is typically performed by a glazier or general maintenance technician using basic hand tools. Before replacing the handle, close and secure the window sash and ensure the casement operator is disengaged. Remove the existing handle hardware and mount the new handle per the window frame manufacturer fastener pattern. If using the optional security pin, install it after the handle is fully seated and verified to operate smoothly.
