Prime Line Products E 2013 Mortise Lock Patio Door

Product Description

The PRIME LINE PRODUCTS E 2013 is a steel-construction mortise lock designed as a replacement for mortise-style, surface-mounted patio door handle sets. It features an adjustable, spring-loaded hook latch projection and is configured for vertical keyway positions when in the locked position. The faceplate ends are rounded, and the rear housing corners are square. Mounting hole centers measure 3-11/16 inches from center to center. This lock is suited for installation by locksmiths, glaziers, and general contractors working on patio door hardware replacement or repair.

This mortise lock is used by W and F patio door manufacturers as well as a variety of other manufacturers. It is appropriate for residential patio door applications where the existing lock body requires replacement due to wear, damage, or loss of spring tension in the latch mechanism. The vertical keyway position and square rear housing corners are key fitment identifiers for this unit. Confirm all four identification points before ordering to ensure correct application.

Key Features

• Steel construction provides durability in high-use patio door applications
• Adjustable, spring-loaded hook latch projection for consistent engagement
• Rounded faceplate ends for compatibility with matching door handle sets
• Mounting hole centers at 3-11/16 inches center to center
• Square rear housing corners — a critical identification dimension for correct replacement selection
• Vertical keyway position when locked — verify against existing hardware before ordering

Compatibility

Used by W and F patio door manufacturers and a variety of other manufacturers. To confirm fitment, remove the existing lock and compare: mounting hole center-to-center distance, faceplate end shape (rounded or square), keyway position when locked (vertical or 45-degree angle), and rear housing corner shape (square or slanted).

Installation Notes

Installation is typically performed by a locksmith, glazier, or experienced contractor. Power tools are not required for most installations, but the door panel must be removed or the handle set disassembled to access the mortise pocket before swapping the lock body. Verify the replacement lock matches the existing mortise pocket dimensions and all four identification features before final installation. Do not force the latch mechanism during fitment, as this may damage the spring-loaded hook assembly.
