Prime Line Products H 3893 Casement Window Tee Crank Handle

Product Description

The PRIME LINE PRODUCTS H 3893 is a 2-pack bronze diecast tee crank handle set designed for universal casement window operator service. Each handle attaches to the window operator spindle using an included adapter, then locks in place with a set screw. Five adapter bore sizes are included, with two adapters per size, allowing the H 3893 to fit a wide range of casement operator spindles. Weighing 1.9 pounds for the packaged set, this hardware is a practical stocking item for window service techs and maintenance contractors working across mixed residential window inventories.

This tee handle set is suited for residential and light commercial casement window maintenance and replacement applications. The universal adapter system eliminates the need to stock multiple handle SKUs for different operator brands. Installers replacing worn or broken crank handles on existing casement windows will find the five included bore sizes cover the most common spindle dimensions encountered in the field. The bronze diecast construction provides durability appropriate for repeated daily operation.

Compatibility

Designed as a universal replacement tee crank handle for casement window operators. The five included adapter bore sizes — 9/32 inches, 5/16 inches, 3/8 inches, 3/8 inches (special), and 11/32 inches — are intended to fit most standard casement operator spindles found in residential and light commercial applications.

Installation Notes

Installation is typically performed by a window service technician or general maintenance contractor. Before replacing the handle, ensure the window sash is fully closed and the operator is disengaged from the sash arm where possible. Select the adapter bore size that fits snugly over the existing operator spindle, seat the tee handle over the adapter, and tighten the set screw firmly to secure the assembly. Do not overtighten the set screw on plastic or soft-metal spindles to avoid damage.
