Prime-Line C 1280 Mortise Style Sliding Patio Door Handle Set – White Diecast, Non-Keyed, 3-15/16 in Hole Spacing

Product overview

Refresh your white sliding patio door with the Prime-Line C 1280 Mortise Style Handle Set. This two‑handed, white painted diecast pair combines a clean, cohesive look with straightforward DIY installation. Designed to work with doors that have a mortise style latch, the set provides a reliable, non-keyed handle option that can be upgraded later if you choose. It is built to fit on doors that are 1-5/8 inch to 1-3/4 inch thick and feature 3-15/16 inch hole centers, making it a practical replacement for worn or damaged hardware while maintaining a consistent door aesthetic.

• Fits door thickness from 1-5/8 to 1-3/4 inches and hole spacing of 3-15/16 inches
• All installation hardware included and ready to fasten by hand tightening
• Mortise style compatible with many mortise latches (latch sold separately)
• Non-keyed by default, with available options to convert to keyed locking using additional Prime-Line components

Easy installation and fit

Finish, style, and compatibility

The white painted diecast finish helpfully blends with white doors, delivering a seamless, nearly invisible aesthetic while maintaining reliable operation. This mortise style set is ideal for doors that use a mortise latch and are prepared to pair with compatible locking components sold separately. Be sure to review the line art and measurements to confirm hole centers and thickness before ordering.

Practical notes

Important: a mortise lock is not included with this set. If you anticipate needing a keyed option later, Prime-Line offers components that can convert this non-keyed set to a keyed‑locking configuration, using the appropriate mortise lock (sold separately). This flexibility makes it a solid choice for updating an older door while keeping the original door profile intact.
