Prime Line Products H 3968 Tee Handle Crank 3/8 Inch Spline

Product Description

The PRIME LINE PRODUCTS H 3968 is a 2-pack tee handle crank designed as a replacement for casement window operators. Each handle features a 3/8 inch spline socket and a contour base design intended to reduce interference with window blinds during operation. Constructed from zinc diecast with a stone color finish, the H 3968 is built for durability in residential window hardware applications. This part is installed by glaziers, general contractors, or knowledgeable homeowners performing casement window hardware replacement.

The H 3968 is suited for residential casement window applications where the original operator handle has worn or broken. The contour base profile is specifically engineered to clear window blind hardware, making it a practical choice in retrofit situations where blind clearance is a concern. The stone color finish blends with common window frame finishes found in older residential installations. Each pack contains two tee handles, covering a pair of windows in a single purchase.

Installation Notes

Installation does not require specialized trade licensing but should follow the window manufacturer's hardware replacement guidelines. Before servicing, ensure the window sash is closed and secured to prevent movement during handle replacement. Basic hand tools are sufficient for most installations. Verify spline socket size on the existing operator shaft before installing to confirm fitment.
