Filler Plates & Wrap-Arounds – Retrofits and Modifications Made Easy
Posted by ZenSupply Product Guru on Jul 24th 2025
Clean Up Door Preps. Save Time. Stay Secure.
In the real world, doors don’t always match the hardware. Whether you're converting from mortise to cylindrical, covering up old prep holes, or reinforcing a damaged lock area, filler plates and wrap-around plates are the retrofit solutions that save the day.
At ZenSupply, we stock a complete lineup of retrofit hardware that simplifies field modifications and restores structural integrity without costly frame or door replacements.
Whether you’re upgrading security hardware, correcting a mismatched lock prep, or rehabbing old frames, ZenSupply makes it EASY to get the plates, wraps, and conversion kits that help you work faster and smarter.
Why Filler Plates & Wrap-Arounds Matter
When door hardware is removed, replaced, or upgraded, you’re often left with holes, cutouts, or mismatched preps that can compromise:
- Security – Exposed holes weaken the door or invite tampering
- Functionality – Hardware won't seat properly without a flush surface
- Appearance – Visible gaps or rusted cutouts look unprofessional
- Fire Rating – Unpatched penetrations may violate code
Filler plates and wrap-arounds restore structural integrity, aesthetic continuity, and code compliance with ease.
