National Marker N344846 Adjustable Door Guide 3-piece

Product Description

The NATIONAL MARKER N344846 is a 3-piece adjustable door guide designed to support bypassing sliding doors with a thickness range of 3/4 inch to 1-3/8 inches. The guide positions the two outer sections at the correct spacing using a cardboard shim during installation, ensuring the door tracks and slides without binding or misalignment. Mounting hardware is included in the pack. This type of hardware is typically installed by finish carpenters, general contractors, or maintenance technicians during door installation or service.

The N344846 is suited for residential and light commercial sliding bypass door applications, including closet doors and similar panel configurations that require bottom or side guidance. The adjustable design accommodates doors at the thinner end of standard residential door stock up through heavier hollow-core and solid-core bypass panels. Because mounting screws are included, no additional fastener sourcing is required for a standard installation.

Installation Notes

Before installing or replacing a door guide, ensure the door panels are removed or safely secured to prevent movement during work.
