Thick Door Kits: Essential Extensions for Custom Entryways
Standard architectural hardware is typically engineered for a door thickness of 1-3/4". When your design calls for the weight and presence of a custom 2" to 2-1/2" door, standard components will not reach. Our collection of thick door kits provides the specialized mechanical extensions required to install Schlage and Baldwin hardware on oversized doors without compromising security or aesthetics.
Baldwin Extension Hardware
Known for their substantial forged brass construction, Baldwin Estate and Reserve series often require specific kits for luxury custom entries:
- Spindle Extensions: Precisely machined to ensure interior levers and knobs operate with Baldwin’s signature smooth action.
- Cylinder Tailpieces: Extended components for deadbolts and mortise locks to ensure full key engagement.
Schlage Technical Solutions
For homeowners utilizing Schlage’s trusted security, our kits offer a seamless fit for modern and traditional series alike:
- B-Series Deadbolt Kits: Essential for extending high-security deadbolts to fit thicker door stiles.
- F-Series Handlesets: Specifically designed mounting bolts and pins to adapt front door grips for oversized panels.
Preserving Mechanical Integrity
At Coastal Hardware Store, we only stock authentic manufacturer extension kits. Using "aftermarket" or makeshift screws can lead to stripped threads, sagging handles, and potential lock failure. By using the correct thick door extension kit for your specific brand and model, you maintain the manufacturer's mechanical warranty and ensure that your hardware feels as solid as the door it's mounted on. Whether you are specifying hardware for a new custom build or retrofitting a substantial entryway, our kits provide the precision needed for a flawless installation.
