The KWIKSET 300T-3 is a privacy-function door knob lock designed for interior residential doors such as bathrooms and bedrooms. It includes a 6AL latch and an RCS strike plate, providing a complete installation-ready assembly. The Tylo knob style ships in a Bright Brass finish. At 1.05 pounds, it is a lightweight single-unit replacement or new-installation hardware set suited for residential door prep work. A licensed locksmith, general contractor, or experienced finish carpenter typically handles installation as part of a door hardware package.
The 300T-3 is intended for interior privacy applications where a locking function is needed without keyed access — standard in bathrooms, bedrooms, and similar private spaces in residential construction. The included 6AL latch and RCS strike reduce the need for additional hardware procurement on the job. It is sold as a single unit and is appropriate for both new construction rough-in and retrofit replacement of worn or outdated interior knob sets.
Designed as an OEM-style privacy knob set for standard residential interior door prep with a 2-3/8 inch or 2-3/4 inch backset latch bore, typical of most residential hollow-core and solid-core interior doors.
Installation is typically performed by a finish carpenter, general contractor, or licensed locksmith. Power tools are not required, but a flathead and Phillips screwdriver, as well as a tape measure, are standard for this work. Confirm door bore diameter and backset measurement before installation to ensure proper latch and knob alignment. No electrical shutoff or gas isolation is required for this hardware type.
