TPard Antique Interior Door Knobs Mortise Lock Set – Matte Black, Skeleton Key, Fits 1-3/4 Inch Doors

Bring authentic vintage detail to interior doors

TPard's Antique Interior Door Knobs Mortise Lock Set blends old-world craftsmanship with practical interior hardware. The matte black finish offers a timeless, versatile look that suits restored furnishings as well as modern spaces seeking a vintage accent. This isn’t just about appearance—it delivers a tactile experience: the weight of the metal, the snug fit of components, and the satisfying turn of the knob and the click of the latch.

Designed for interior doors, this mortise lock set is built to fit doors from 1-3/8" to 1-3/4" thick and a 2-3/8" backset. The faceplate and trim plate screw holes align with common profiles, but please compare your current door measurements before purchasing to ensure a proper fit. The kit serves as a complete replacement option for damaged hardware or for upgrading a vintage door with a functional locking mechanism.

Core benefits and what you’ll receive

• Two sturdy knobs and two trim plates deliver a balanced, symmetrical look on both sides of the door.
• One mortise lock body provides the locking mechanism, while two skeleton keys offer optional, vintage-style operation.
• Backset compatibility at 2-3/8" supports common interior door configurations.
• Reversible latch allows left- or right-handed installation, aided by included instructions.
• All essential components are included for a DIY installation: square spindle, strike plate, screw pack, and more.

Practical notes for installation and use

• Carefully open the cover to avoid losing small spring-loaded parts; photos help preserve the internal structure during setup.
• Ensure you’re working with interior doors only, as exterior-grade security features are not specified here.
• Follow the included instructions for the precise layout of screw holes and backset alignment.
• The skeleton keys activate the lock bolt, offering vintage charm with practical control inside your space.

Whether you’re restoring a period room, refreshing a cottage vibe, or simply replacing a broken knob, this set provides a historically inspired look with modern convenience. It’s a compelling option for projects that value character, durability, and a straightforward DIY upgrade.
