Thick Door Kits – Customize Your Hardware for Oversized Door Thicknesses
If you’re working with doors that exceed standard thicknesses, you’ll need the right components to ensure your hardware fits and functions properly. That’s where our Thick Door Kits come in. These specialized kits are designed to adapt door hardware like levers, knobs, deadbolts, and entry sets for use on thick doors—typically ranging from 2-1/4" up to 3" in depth.
At Coastal Hardware Store we supply thick door kits from top brands including Schlage, Baldwin, Sure-Loc, and more—so you can ensure a perfect fit with the hardware you’ve selected.
These kits typically include extended spindles, longer mounting screws, and customized tailpieces to accommodate the increased thickness of solid wood, insulated, or custom-made doors. Whether you're installing:
- Entry handlesets for oversized front doors
- Mortise locks on heavy or insulated doors
- Interior levers or knobs on thicker bathroom or closet doors
Our thick door kits help bridge the gap between standard hardware and specialized doors—ensuring smooth operation, secure locking, and seamless installation. If your door thickness falls outside the 1-3/4" standard, these kits are essential.
Not sure if you need one? Check the specs on your selected product page, or contact us for compatibility advice. Many of our hardware collections include thick door kit options during the ordering process—but if not, you can find the compatible kit here.
We offer thick door kits to match finishes like matte black, satin brass, oil-rubbed bronze, polished chrome, and more—ensuring a coordinated look, even with custom hardware applications.
Whether you're outfitting an entry door on a custom build, retrofitting historic doors, or dealing with extra insulation or paneling, our Thick Door Kits provide a reliable, manufacturer-approved solution for extending hardware functionality—without compromising performance or appearance.
Frequently Asked Questions About Thick Door Kits
What is a thick door kit?
A thick door kit is a set of extended components—like screws, spindles, and tailpieces—designed to adapt standard door hardware (such as levers, knobs, and deadbolts) to fit doors thicker than the typical 1-3/4". These are essential when working with solid-core, insulated, or custom-built doors.
What door thicknesses require a thick door kit?
Most standard hardware is made for 1-3/4" thick doors. If your door is 2", 2-1/4", 2-1/2", or thicker, you’ll likely need a thick door kit to ensure the hardware functions correctly and installs securely.
Which brands offer thick door kits?
At coastalhardwarestore.com, we offer thick door kits compatible with Emtek, Baldwin, Sure-Loc, and other leading brands. Always check compatibility before ordering.
Can I buy a thick door kit separately?
Yes. If your chosen product doesn’t automatically include the correct size or thick door option, you can order the compatible kit separately from this collection. Each product listing includes finish options and supported models.
Do I need a thick door kit for interior doors?
You may. While thick door kits are most commonly used on front and exterior doors, some interior applications—like oversized custom barn doors, paneled doors, or double doors—may also require one depending on thickness and hardware type.
